Simple question: Did you upgrade the Internet Explorer recently? Or any security update recently?<br />
<br />
<br />
This might not be &nbsp;the reason your RDP stop working, however I remember a occasion where internet explorer upgraded to IE 8 and all of sudden RDS stops, If yes, even if you uninstall the updated version of IE, that doesn’t help.<br />
<br />
Let me know the answer for this question, if not we will find the actual cause!!

The servers have not updated to IE 8 but they have recently received security updates. That is what I suspected might be the issue as nothing else in the environment has changed but I do not have any idea which one may be causing the issue.

Periodically the citrix servers stop accepting connections and then eventually they will not accept an RDP connection and have to be robooted several times or powered completly down and back up. The citrix version is 4.0, the OS is windows 2003. We have some servers running windows 2000 who are not experiencing the issue. Could it be related to a windows update?
