Error 651 with PPPoE connections in Windows 7

I did the above and my modem has stopped functioning. There is a yellow exclamation in device manager over the modem driver.
I am running windows 7 build 7100 and a Reatek RT8168C lan card. Any other suggestions?

How do you bypass TrustedInstaller so as to change the file name?

Also tried this method, but didn’t work.

I uninstalled MS Virtual PC 2007 and did a reboot… problem solved !

I uninstalled MS Virtual PC 2007 aswell and problem solved..!

its really gud // ts in layman language

Have had no success connecting Windows 7 Home Ed (final ed) to the internet with USB ADSL Modem – always get Error Code 651. Have tried x2 Modems (Zoom / Thomson 330) but exactly the same problem. HELP

Tried this fix but no joy – same error (651). Even tried x2 different USB ADSL Modems (Thomson 330 / Zoom) – after downloading suitable (Vista) drivers . . . . and even though Device Manager said both modems were working . . . I get the same error.

Basically – help. Win7 looks good but without ADSL USB Modem connectivity to the Internet, there are going to be thousands of angry people . . . once they use a friends computer !

Couldn’t perform fix. Couldn’t get around “TrustedInstaller” window.

yes. seems like just uninstallaing microsoft virtual pc 2007 solves the problem.

where i can find ms virtual pc? i already reinstall my os but still no luck…

Same problem as described above. No joy by changing raspppoe.sys and cannot get round the ‘trustedinstaller’ window. Does anyone have a better solution?

I have tried to find the Microsoft Virtual pc 2007 by searching tool on my computer, but still got nothing. can anyone tell me how to find the MS Virtual pc 2007 then I can uninstall it. please!!!

I have the same problem and have run into the same trustedinstaller issue. What else can be tried, or how can I work around that?

Hi all,

I’ve got the same problem as well. Tried several options: different routers/modems, LAN, wireless, changing the raspppoe.sys file to Vista –> none has worked so far.

I can not find the program MS Virtual pc 2007 on my Sony Vaio. Does Microsoft really don’t have a solution for this?
Since my laptop can’t connect to the internet, I don’t know if Microsoft released a patch or something for this problem. Have they?

Thanks for any advice

Brand new netgear modem but it will not connect to cable modem. My old netgear works fine. I don’t think it is a windows 7 problem but someting in the modem as the old one works fine. You don’t even have to have the wireless connected to a computer for it to find the cable modem if it is working properly. So if when you are trying to set up the new wireless it has to find the cable modem and internet connection inorder to not give you the 651 error. Now how do you correct that?

My vista pc did not display my nokia 6275 modem hence unable to dial, shows error 651. Please help

Hade the same problem (erroer 651). Nobody could help.
Try this- Start, control panel, PROGRAMS(uninstall a program), Turn Windows features on or off . Now check to see if the relavant checks are on. [internet information services hostable web core] was unchecked, why windows 7 turned it of I dont know, but when I tunerd it on my connections worked.

Hey Buddy ur Resolution With ras Dwd , Fixed My Comp.. My Win 7 Is Working Perfect !!

Trying to switch hi speed internet Cableone) from XP to Windows 7. Get error 651. references modum problem. Would appreciate comment

First: ppl who are talking they cant get all the rights Trusted Installer has you are idiots! Dig some more! Computer is a great thing, when you are from this age!
Second: the thing with file you talking about is not working, but i know how to solve this problem, write me !

Had the 651 error but did a fresh reinstall of win 7 and it seems to have fixed the problem.

If you were as desperate as i was you might wanna give it a try

I had the “651″ error, changed ([internet information services hostable web core) by turning it on. Did not do any good. Went in and Changed the raspppoe.sys as was suggested and now get a 797 error.I have some programs that can’t see the internet and some that do. I can get on using the wireless option but I want to use ethernet cable.
** to change the raspppoe.sys you have to right click on the file and go to properties and change access levels.

there are lots of questions here but where are the comments about these questions i am interested in Comment by Geoff Jarratt on August 11, 2009 @ 1:27 am

I can’t beleive it: I uninstalled Virtual PC 2007 and it made the trick. My VPN is working again. Thanks.

seriously, i cant find virtual pc anywhere so if you dont have it i guess you don’t have to uninstall it but i still get the error, and there are no answers to all these questions… ridiculous!

please check local area connection, make sure it’s enable.
called customer service of my dsl provider. he guided me to this and solive my error 651.

hey guys I have this problem and I tried to change name of folder but I can’t coz permission and i tried to change permission but it was all hidden and cannot edit so pleeeeeeeeeeeeeeeeeeeeeeez i buy laptop new with Win 7 and the connection yesterday working but today not work and error 651 appear…!!! i try another laptop OS XP its working on internet but my lap not work … any help it will be welcome

Hi guys, can someone tell me where is Vitual PC program? Cant find it…
Thanks

cmd.exe with administrator option (regithclick upon de icon) > write: “takeown /F C:\windows\system32\drivers\raspppoe.sys”
> open explorer an go there > finally, change the name of the file.

note: its useless, because then you need a WAN miniport adapter and there is no driver for it. So its seems a message microsoft… “¡¡CHANGE YOUR OLD USB MODEM, AND GET A ROUTER!!”.

¬¬ I hate them xDDD

hi all,
ras solution not working…. nothing changed and still receiving 651 error., plz advise

hi all,
i think until this moment no solution for this problem !!!!
how microsoft produces OS suffering of multiple errors!!!!!??????
down shit…

This is for all the Newbs in this post and those that where guessing at the solution to the 651 error. The reason for this error is due to people using the “Setup new connection or network” option in the Netwrok and internet center control panel. THIS IS WRONG!!! do not use this unless you are setting up a VPN. If you are not setting up a VPN leave this ALOWN!!! Windows 7 needs no netwrok setup to connect to a “Broadband connection” or otherwise call the “Always on” service. Instead go to properties and delete the setting out of the connections table that you have put in by using the remove button after selecting the connections, then simply power cycle your modem and computer in that order to let windows 7 config the connection for you.

That is all you ever had to do!!!
Laters Master Matt

please Master Matt explain the solution, what we need to delete from setting?
i want to tell you i tried to connect by VBN like this step:
set up new connection or network->connect to the Internet->
set up new connection->PPPOE-> “Connection failed with error 651 ” , but when I connect another PC it’s connect direct without any configuration because all of conig in router…
so please help me to solve this problem>>>

Matt is absolutely correct. Windows 7 needs no network setup to connect to a “Broadband connection” or otherwise call the “Always on” service.
Trying to run “Setup new connection or network” option, while not setting up a VPN, in the Network and internet center control panel while trying to fix a 651 error is never going to work. The simple solution to his error is to make sure your on a home network in the network and sharing center in your active networks as you prob never let win7 configure your setting for you on he install or you chose to have win7 set your networking settings to the public settings.

Ehab
Once connected 7 identifies connection, labeling Public network, if as you say “changing to a home network” will fix this 651 error then how do you change it?

Also I never used the “Setup new connection or network” option in the Netwrok and internet center control panel. 7 identifed my wireless connection after upgrading my system from xp but not a new LAN connection??? WTF

my problem is, registry settings in “WAN/ATM/ADSL miniport” MAC address 12 characters with ¬ character. so its like “0015DBA5F31D¬” it has 13 characters.
in device mmngr its show as “FFFFFFFFFFFF”. after remove that character from registry device mmngr show it as “0015DBA5F31D” like vista. but after modem remove and plugin that MAC address replace with that character. this is wht different its that vista.
anyone know anything about i think this is problem bcoz in vista nt like that.

Being new to windows 7, this is what worked for me. I was able to connect via wireless as some people stated, but when I tried to connect via cat5(wired), I received the same error 651. Type in search “connections”, then click on network connections and enable the connection you want to use and disable the one you dont want to use, Windows 7 should pick up all available connections for you on the initial setup. Now that I’ve found it I feel pretty retarded, but while searching through the control panel, I was unable to find all my connections like old window OS’s

this didnt work, also, ssems amusing when you expect someone to connect to the internet to download a file which the problem in the first place is that it cant connect to the network and therefor the internet in the first place!
Windows and micro soft, need to start testing there software before realesing it on the market, its the same story evertime, this is exactly with everyone is switching to linux and apple! customers have had enough of being test pilots !!!

i have one problem with TrustedInstaller but now is fine, tks a lot.

“Master Matt” is absolutely correct – I did the steps that he has listed, restarted the computer, clicked the work off line button (as it was checked) and it came on! Thank you!!

this error can be removed just enabling one option in the modem.
get into the modem (through 192.168.1.1 in most of the cases) then configure it in bridge mode. while configuring there is one option “Enable Bridge Service”, just put a tick on it or enable this option. it will work.

Apparently there are a number of things that can cause a “651″ error. In my case it was happening because I had forgotten to add my mac address to the list of approved mac addresses maintained in the router. I have a Belkin, and the address for accessing it online is 192.168.10.1. I went into “mac address filtering” in the firewall section and added the mac address of my new computer. To make changes you will have to enter your password. At one time you, or someone on your behalf would have had to do this with your old computer, but if you are like me after a month or two you forget. In case you have forgotten, you find the mac address by going into DOS and entering “ipconfig/all”.

A very interesting group of postings and very helpful. Thanx.

Had same error on my girlfriend’s PC.. Master Matt’s advice worked. Had RASPPPOE .dll all ready to go just in case but didn’t have to resort to it.

Just deleted the “extra” connections, and then told it to repair the “Local Area Connection” (it’s all under control panel — list connections… right-click/repair).

I had to go the extra step of powering down the cable modem and restarting it (which Windows told me to do — And what do you know, it was right).

Thanks all for the help!

Do make sure to go into Device Manager and make sure your Network Adapters are all set to enabled.

I had been using a lan connection, upgraded my laptop to 7, then let a friend borrow my lan and all of a sudden I was unable to connect to the internet.

I had tried contacting my apartment’s ISP (they only spoke japanese) and modem maker (they only replied in korean) and microsoft, but not a one mentioned (as far as I could tell anyhow) looking at the device manager.

but in the end I just fixed the problem by randomly deciding to open device manager, and noticing that one of my network adapters had been disabled.

I am not sure if this is going to help you all but I had a customer who had a same problem and was using a Scientific Atlanta modem. We had to delete a broadband connection from network connections and restarted the modem. Here what we need to do. Shutdown the modem and wait for atleast 2 mins. Go to Network and sharing center and go to change adapter settings. Delete any broadband connection created which is for dialup (Which I guess we dont need when we have high speed internet). restart the modem and you should be connected. Please note that this resolution might not work for everyone but hope it helps a few.. I work for Dell.. Have a nice day..

I want to connect my new laptop having windows7 from broadband
connection .
but I have try more times but unable so help me to do this.

Also this may sound silly but just check the wireless switch is turned on – it may be a physical switch on the machine or for netbooks it may be a function key combo

I had a problem connecting my new dell after it worked fine for a couple of months and found out there was button on the top left hand corner, the f2 button that turns the connection on and off. has a symbol of a tower.

Some great comments and ideas, thank you. However, I need to append a clarification to Master Matt’s and Mark’s comments regarding “always on”.

Broadband internet is not “always on”. “Broadband” has nothing to do with the “state” or “method” of high speed connection. Broadband internet is a particular quality of “high speed internet” which is defined on a state by state or country by country basis.

High Speed Internet can be served in a few different ways, here are the three most common (in USA).
1. “Always On” DHCP. Can be w/ or w/o a separate modem-like device. Historically this was through Cable service providers (eg Cox), but other options are available.
2. “Always On” or “Keep Alive” PPPoE. Not technically “always on”. Requires a modem (or router) to manage the connection. Traditionally this has been DSL providers like AT&T.
3. “On Demand” PPPoE. Also traditionally DSL providers.

#2 and #3 are not really service or provisioning differences but they are instead options in the authenticating device (modem, router or computer) on how the device handles the connection process. “Always On” PPPoE is still technically “On Demand”…it’s just not handled that way.

A computer which is connected directly to a DHCP device – be it a “direct” connection to DHCP provider w/o a modem device or a modem+router which is handling DHCP or PPPoE connection – will only need the Local Area Connection enabled and it is true that going through “Create a connection” is a waste of time unless needing VPN.

However, if the computer is connected directly to a bridged modem/router or otherwise having a direct connection to a PPPoE servicing ISP, then using “Setup new connection or network” is not! a waste of time and is in fact necessary. It is this process which Vista and Win7 will create a connection of which the default name is “Broadband Connection”.

If a “pppoe dialer” or “broadband connection” is needed for a PPPoE High Speed service, then you appear to need the raspppoe.sys file. Simply deleting your connection named “broadband connection” won’t help. If your provider set up the “broadband connection” icon on your Desktop or your Network Connections screen…leave it or get with them to replace it, because w/o that icon or connection…you aren’t getting online even if the error is fixed.

There are a host of other ISP configurations possible, I just described the top 2-3 basic, most common setups in the US. Check the internet for more information on ISP types.

i think this has become a worldwide question,and too many people consider that the above way cant solve the problem,so i want to try maxigas’s method,but i wonder wherer can i find the virtual pc 2007??
any help will be appreciated.

none OF solutions worked for me on that forum. and here is what i did than: just change cable conecting modem and pc with ethernet cable! WORKS!

@irene – If you have it, look under add/remove or uninstall programs (depending on windows version).

HI all,
FADOLA ‘s solution worked for me..can’t comment about the renaming of system file in system32.At the same time i asked my ISP technician to reset my ip.After a number of failed attempts..this was the solution that worked..

Thanks!!

windows 7 asks permissions to change rasppoe.sys filename… I logged in as administrator only.

Hi there I’m a technician working for an ISP, while the some of the above information is correct it has been discovered that error 651 can also indicate a time out problem. similar to error 678 and 815 with previous versions of windows. I potential fix for this would be to reset the ip stack/winsock. run your command prompt in administrative mode.

type the following commands

netsh int ip reset resetlog.txt
netsh winsock reset

restart the computer and test.

I have had some success in the past, and this should correct a miner time out problem on the computers end.

I had the same problem, on a brand new sweet gaming pc, with getting online and error 651, and i spent 8 hours trying to fix it without luck. So very frustrated i installed Call of Duty 4, to play the singleplayer (the only game i had that didnt require internet) and when i launched the multiplayerpart from the singleplayer, i was suddenly online…
So the cure for error 651: Call of Duty 4

alright guys the solution to this is deleting the broadband connection that is all , trust me it is all you have to do to fix error 651, here are the steps:
1. control panel
2. network and internet
3. network and sharing center
4. change adapter setting(left hand side)
5. DELETE broadband connection

that is all you have to do!
thanks to master matt

Master Jolaman

I’m still facing problems with my internet connection. I’ve tried: changing ethernet cables, opening CMD and tryping
netsh int ip reset resetlog.txt
netsh winsock reset, Checked Internet information services hostable web core, tried replacing raspppoe but couldn’t rename or delete the file.

CAN SOMEBODY HELP ME? Please? x) Am sick and tired of looking at forums and trying to fix this problem without any solution.

pessoal ja tive esse problema ,’bate cabeça’ com isso,mas consiguir a soluçao,percebi que a maioria dos pc novos

deleting broadband connection..? mine is grayed out and cannot delete it..

oh actually I get error 638 after deleting broadband connection.. dead end..?

hi all,
I m unable to rename rass file it is showing security warning ( Administration permission required)

receiving 651 error., plz advise

This link sorts out the trusted installer issue
http://helpdeskgeek.com/windows-7/windows-7-how-to-delete-files-protected-by-trustedinstaller/

If a connection is grayed out in your Network Connections screen or if you are getting a prompt that “admin permissions are needed”…then get administrative privileges. Talk to the person who manages your computer or a tech. If your login/username doesn’t have admin permissions and you can’t switch and log in as an admin, then you need hands-on tech help.

In Windows Vista or 7 (XP too I think) CTRL-ALT-DEL or CTRL-SHIFT-ESC at the log in prompt might give you the ability to enter “administrator” for a username. This is something I haven’t tried so will need confirmation. (Usually CTRL-SHIFT-ESC brings up the task manager, not sure if it does the same thing at the login prompt.)

@frank – (using Ryan’s suggestion to run netsh reset commands) – You will need to delete and recreate the broadband (the pppoe dialer) connection if your ISP requires you to use one.

By replacing raspppoe.sys makes your internet connection run fine at that point of time but after then when you restart your computer, it gives you a new error 797.

Try changing ‘Public Sharing’ settings and file and printer sharing in the ‘Advance Sharing settings’. I was able to log into the router and the 651 error went away.

Under connections in the Internet Options, select never dial a connection. This worked for me. My ISP refer me to Microsoft but their trick didn’t work, and that was to rename the driver.

Master Matt ,Can u tell me the steps to resolve the problem…”Error:651 Your Modem is reported an error”. AS u said to delete something…
actually what to delete..whether is to delete broadband connection?.If so there is chance of reporting error like 638,which is stated by Jeff.Can u help me plzzzzzzzz.

Matt , i am using Windows 7 os and faced this 651 Error problem

I fixed this problem by one or all of these selecting automatic detect settings, changing static IP to assign an IP, disabling Bonjour service. Making sure “never dial” was selected

I did not replace the raspppoe.sys file.

all rubbish.. jus talk to ur ISP dealer..
i faced d same problem.. but was solved..

Did I mention there were 2 other computers both XP that were connected to the same Linksys router and Comcast modem that were working with no problems. So the ISP was not the problem at all.

friends…….i solved this problem as…my desktop is win XP and my laptop is WIn 7. I created a new dial-up connection in my laptop and tried to connect through wireless way…mean time i disconnected the dial up connection in desktop temporarily.That’s all NET is connected.”I found that both my desktop and laptop are not able to connect simultaneously.”
If still problem is there for you.give an IP for DNS server, default gate way and try the above method.IF still problem is there contacting your ISP dealer is best

Thanks for the great help.

Go to Modem Configuration Page at 192.168.1.1

Enter User name And Password

Go to Configuration-> Internet

There will be somthing like pppoe 0_35
with Disconnect written under it.

Click on the Dustibin icon to delete it.

Then click on Add.

In VCI change from 38 to 35

Click on next

Select Bridging in protocol and Select LLC/SNAP
in Encapsulation Type.

Click Next

Click Next again

click on Apply

This Will Work For Sure….

Wisest word so far was that 651 can have different causes, although most of them related to W7′s behaviour in one or another way, probably. In case it helps someone

THIS IS WHAT WORKED FOR ME (with you it might be different, though):

Following restart procedures I finally got a dialog window that enabled me to remove ‘broadband connections’, connections icon in taskbar>right click on item>[properties] did NOT give me the option to remove, at last not as the type of user I run this session at, and I’v not investigated changing this.

What brought the real help was ENABLING the ethernet card, which was disabled, who did it ?
The challenge was getting there.
START>control panel> and then things are getting very ‘dynamic’- different control options are grouped in very changing ways according to how you click your way through the options. What you need, is the “device manager”, and probably SYSTEM and HARDWARE are terms that will help getting you there.
Once there, things look familiar again, a file-tree-like display should show the devices, if not: View>devices by type.
>find ‘network adapter’, open, find your ethernet card, and
-right click and enable if disabled, or
-try opening and clicking your way around .

I found under Network adapters a ms virtual wifi miniport adaper, am I right that this is a good thing to get rid of? And was this post helpful?

What is the reason for this ’651′ error come in only windows 7 & vista?

thnx “sdasdas@gmail.com” for ur bridging technique…
its worked…!!

those having the f**king error 651 can try this bridging
technique….!!

Thnx bro.!!

Charlie, that was the trick!

I was connected to my modem but didnt get any internet acess. When I disabeld all the settings in public shring it suddenly worked! Thanks!

(Control panel->network and internet->network and sharing center->chose sharing settings->advanced sharingsettings->public settings.. Im using swedish windoes, so the locationnames may differ)

“Try changing ‘Public Sharing’ settings and file and printer sharing in the ‘Advance Sharing settings’. I was able to log into the router and the 651 error went away.”

I have Wi-Fi router working in Access Point mode. After installing Win7 x64 my wireless network adapter (RTL 8185 chip)was already successfully defined and was able to connect to router. But PPPOE connection to ISP returned 651 error. None of all solution above wasn’t worked for me. I’m wondering that driver from Realtek for Win7x64 doesn’t help me too.

Problem was solved when i had install original driver from manufacturer for my wireless adapter. Solution for me was driver downloaded from:

Hope this help!

Thanks, now it’s fixed

Hi
I Cant To rename that file (windows dont let me)
please Help

Hello. I apologize for not really speak English well
My problem is the same as the others.
PC / Thomson Modem / Belkin WiFi Router
The problem for me is 651.
I do not understand what to do and how to delete a broadband connection.
raspppoe.sys file exchanges were carried out.
but then the 797 error appears.
What is more to be done?

I’m in error 651 hell… I have yet to get online with my new PC. An Alienware idiot, who didn’t know that you have to put spaces between things in some command prompt lines (“No, you need to type it exactly as I say, no spaces!”) tells me (after four hours of reading google results to me… seriously, he had no knowledge of computers) it’s the ISP. The ISP (Charter) sends install guys instead of tech guys; they look at the computer, nod to each other, and say, “It’s the computer.” They did zero troubleshooting. Basically, I’m getting an IP address starting with 169. If I try to release and renew the IP address from the command prompt (run as admin, of course), it will release, but it hangs on renewing and I never get further than that.

Help!!! I really want to use my PC.

Hi.

I experienced the same problem just 3 days ago. I read most options and finally decided to go old school and do a System Restore and my “Error 651″ was solved. I’m not sure if the recent Windows update is part of the problem which I got the day before. After Sytem Restorem, those same updates came but I haven’t installed them, if I do and the bloody ERROR happens again. I’ll holla!

I also called my internet server and they told me they tried all solutions with other customers and nothing worked. The technical guy I spoke also told me that because its a Windows 7 bug problem it will keep coming back even if I re-install windows 7.

The only solution it seems, is for Microsoft to fix the bug.
I hope this helps:-)

Here is What i tried it worked for me. PS: I use Win7 HomePremium (Turkish Lang).

Start
Control Panel
Internet And Network thing
Network And Sharing
on the left side you will see Change Adapter Setting
Now that were here turn on your Local Area Network
Go back and start a new network
Broadband (PPPoE)
Enter your ISS name and Password
There you go !

Do not listen to Juddah’s advice. The settings he suggested people change are ISP specific and if you change your modem’s VPI/VCI setting from 0.35 to 0.38 or something else you may only find yourself in more trouble.

That number in the modem MUST match what your ISP uses. If you change it you may be able to connect but you won’t be able to view webpages, and routers usually won’t connect

Thought I would chime in with the solution to my win7 internet connection error issue [651].

Bought a new Compaq desktop [cq5500f] with Win7 home premium, to replace my old WinXP desktop, that right out of the box could not locate the internet/ISP when wired directly with my Uverse router 3800hgv. Which had previous worked fine on my WinXP desktop. Even though I would continually receive the 651 error in win7, I could ping all my default and gatway IPs in the command prompt, and even google.com. So it seemed obvious that it was a Win7 OS issue.

Anyway, after reading this entire thread I decided to first use a windows restore point, and then reset/rebooted my router. I then tried taking Fadola’s advice: “Try this- Start, control panel, PROGRAMS(uninstall a program), Turn Windows features on or off . Now check to see if the relavant checks are on. [internet information services hostable web core] was unchecked, why windows 7 turned it of I dont know, but when I turned it on my connections worked.”, but still no internet [though still good advice in my opinion]. In the end and after trying all that, here is what ended up solving the problem for me…

Uninstalled Microsoft Silverlight and the Norton Antivirus software that came with the pc and viola, rebooted and my internet was found immediately!

Hope that helps a few! FYI – I never was able to update/replace the raspppoe.sys file, but regardless, it didn’t seem necessary in my case. Take care and good luck!

I have had the same thing, modem was a problem, when I changed the modem error dissapears, it works now perfectly (wireless key was brake as well, we changed it few times, didnt want to work…now its perfect…so, maybe this is the thing,dont make any experiments, just chabge the modem…:-)
