RDP Fails - No Error message

[Guest sp2nue@gmail.com]

Folks, I am having a very strange problem with Win 2003 server and

RDP. RDP will work normally without problem for a few days, and all

of a sudden it will just stop working without any logging or error

messages.

 

The symptom is that when a client tries to connect to the server, the

normal prompts are presented on the client, and when it tries to

establish the connection, the client just disappears without an

error. Normally, the client would bring up the window and a session

would start, but in this case, it just dies. When this happens, no

one can connect and my only option to re-enable it is to reboot the

server, which is not a very elegant solution and also difficult to do

during production hours.

 

I've done network traces and the RDP packets are getting thru to the

server, but they just stop for some reason and everything aborts

without anything going in the log on the server or reported back to

the client.

 

Any pointers on helping to resolve this much appreciated. This is an

8 cpu 16gb ram box. It had VNC at one point, which is disabled now

because I initally thought this was causing the problem, and once

disabled it started working fine for about a month, then started

happenning again with no known config changes made.

 

Any help appreciated!
