IPv6 is enebled by default in Windows Server 2008. If you are not using IPv6 then this can be disabled from the Windows Registry as follows:

Click Start – Search and type “regedit” and press enter. This should launch the Registry Editor.

In Windows Server 2008 Core installation, run “regedit” from an elevated Command prompt or as an Administrator. This should launch the Windows Registry Editor.

Navigate to the following rgeistry key

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]buy propecia online



In the right-pane, right-click, select New – DWORD Value. Enter the name as “DisabledComponents” and set its value as “FF” as shown below. Once done, restart the Server for the changes to take effect. If at a later time, you want to revert the changes simply delete the key and reboot the server.

  1. internet secuity sating & not download

  2. Registry might be DisabledComponents not DisabledComponent
    I realize that this article states Vista: http://support.microsoft.com/kb/929852
    But, I am fairly certain that it is DisabledComponents on the DWORD name for Windows Server 2008 also.

  3. Is this entry supposed to be there if you go into the properties of your NICs and disable IPv6 there?

  4. It should be DisabledComponent. http://support.microsoft.com/kb/952842

  5. It should be DisabledComponents with an ‘s’ at the end..

    Both articles say so;

    i just field tested this on Win08R2RC1..

  6. Just had a Microsoft Engineer on site to give us a 2008 Active Directory class and he was very adamant about “NOT” disabling IPv6 in 2008, EVEN IF YOU DO NOT USE IT! Apparently you can cause yourself a lot of headache later if you do disable IPv6. He suggests leaving IPv6 enabled at all times if you are working on or Migrating to a 2008 AD environment.

  7. Hello,

    Why does the items still show in the NIC properties? I understand that it’s “disabled” after the regedit, but as most of you will experience, another admin will run across this and waste time trying to question weather or not ipv6 should be disabled even though it it. ;)

    Why does this article provide a value of “ff” & M$ article says to use “ffffffff”???

  8. anyone still around? Ideas???

  9. fyi…

  10. Yes it is DisabledComponents (with the s) been doing this for quite some time. This is a crucial step when installing Exchange 2007/2010 as it “yells” at you when you have a network connection not statically assigned.

  11. This doesn’t affect me as I don’t expect to be around in the year 20008! ;¬)
