I have a Windows 2003 Terminal Server in Application mode.
It has been working correctly for about 3 years with no issues. Suddenly, this morning it is no longer accepting connections.
Things I have tried:
netstat -an: server is NOT listening on 3389
Terminal Services service: running
No firewall running on server (on same subnet)
Remote Desktop Users Group has all of the correct users in it.
No errors in event log that have to do with Terminal Services
I've check the registry entries and they all look correct.
Disabled virus protection - same result
Reset TCPIP stack - no help
One thing that has something to do with the issue, but I can't figure out exactly what:
When I open the Terminal Services Configuration managment console and look at the properties of the connection ... if I click on the Network Adapter tab, the mmc hangs and has to be forcibly killed. I deleted and recreated the connection, but the same thing happens.
This has the entire office down, so any help is GREATLY appreciated!!
