This is using Terminal Server application mode to support 10+ client connection using ms windows 2008 r2 server. User always faced the connection hung a few times per day. From the system event logs, I found 2 related events:
The terminal server security layer detected an error in the protocol stream and has disconnected the client.
The rdp protocol component x.224 detect an error in the protocol stream and has disconnected the client.
Please see the actions i did:
- update network card driver
- check that nic is configured auto-negotiable
- Open RDP-Tcp properties, and change the layer to “RDP Security Layer” rather than “Negotiable”
As for the rdc, most of the users are using version 6.3.9600. I am currently monitoring now. What else could be the problem?
