when you use Remote Desktop Connection on a Windows 2003/XP/2000 Professional computer to connect to a Terminal Services server.You may receive the following error

The RDP protocol component “DATA ENCRYPTION” detected an error in the protocol stream and has disconnected the client.

A potential race condition between the Icaapi.dll and Rdpwsx.dll dynamic-link libraries (DLLs) may cause the private certificate key on the Terminal Services server not to be synchronized.

Click start—>Run type regedit click ok

Locate and then click the following registry subkey

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TermService\Parameters
Under this registry subkey, delete the following values

Thank you so much. I searched for 4 days before finding this, and it worked. My issue arose when I found spyware infected files in roaming profiles on a client’s Server 2003 machine. After cleaning the spyware (OnlineGaming) the RDP failed. I thought that the spyware may have messed up the encryption for RDP, but not so. This fix worked. Thanks.

I am getting the above error on my terminal server.”The RDP protocol component “DATA ENCRYPTION” detected an error in the protocol stream and has disconnected the client”. I am using Server 08. I cannot find the registry entries mentioned above. Any help would be appreciated.

I was pulling my hair out (what’s left of it) trying to figure out what was causing the RDP error. I ran regedit, and didn’t find those specific values, but I did find a single value named “certificate.” I deleted it, rebooted the PC, then tried the RDP again, and voila! It worked like a charm.

Thanks so much! (You made me look like a genius.)
