Access to the terminal server via Remote Desktop Protocol (RDP) freezes or hangs when a roaming profile is used. No other applications were installed except remote desktop services with a normal CPU usage on the terminal server.
At times when the RDP gets access, an error message appears:
User Profile Service
Your roaming profile is not synchronized completely with the server. You have been logged on with a partially synchronized profile. Please see the event log for details or contact your administrator.
This issue occurs when an OfficeScan (OSCE) client is installed on Windows 2008 R2 Terminal server.
To resolve this issue, disable TCP chimney offload:
- Open the command prompt with administrative credentials.
