W2K3 Terminal Server Not Accepting Connections

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!!

Is your server service running and netlogon?
Yes Server and Netlogon services are running.  I have restarted them to no vail and rebooted the server a couple of times with no change.
What errors/warnings are showing up in the Application & System log for the server?
How is your disk health, the hanging of your mmc sounds like a problem with your tcp/ip cable/files/other dependancy's. If you unplug the cable can you then open tcp/ip settings?
@PenquinN good track, NIC card too.
I can open the NIC card setting, etc without issue.  It is only when I try to look at the Network Adapter tab in the Terminal Services Configuration that is hangs.

I'll check the issue with the cable unplugged and let you know.
Does anything show up in the event logs?
There are no errors showing up in the event logs about the terminal services.
Is your server patched to the last updates?
the Server has on Service Pack 1 becuase the vendor whose software runs on the server had not "certified" SP2.  I spoke with them and they agreed I could update to SP2, but when I attempt the install it starts and hangs at Inventorying Your Hardware and never proceeds.  It allows you to cacel the install, but the process never terminates.

Also, I sttempted to restart the NETLOGON and SERVER services. NETLOGON worked fine, but SERVER failed to restart.

I unplugged the NIC and attempted to look the Network Adapter tab in Terminal Services Configuration, but it still hangs.

Still no TS errors in the event logs.

I ran devcon.exe -r install %windir%\inf\machine.inf root\rdpdr ... it ran then rebooted the server and still no joy ....
Ok, the problem is solved.  I ended up bring Microsoft in to help resolve it.

The problem was a faulty print driver that had been installed that hung the print spool and ended up blocking all requests to port 3389.

We pruned the print hive, reset all of the print monitors to default and that resolved the issue.
