Intermittently we get a problem where a remote desktop session will get disconnected with the error message “Because of a protocol error, this session will be disconnected. Please try connecting to the remote computer again.”

We are getting this with one server only which is running Windows Server 2008, connecting with Windows 7 clients. The session itself stays running, you just get disconnected, and you can try and reconnect. Sometimes you get in for a while then it will kick you out.

We are connecting from Windows 7 clients. We have tried connecting using Cord on a Mac and this works fine, so it’s not like the session itself is corrupted.

One problem is that there are some critical applications running under the session (I know, let’s not discuss the idiocy of that), so we cannot reset the session in any way during the working day – so any diagnostics must have minimum impact.
