The remote desktop and citrix management console show the user as Active, but it can close the session.The users that have active sessions CAN work.When it occurs other users CAN log in, but any user that try log off get this message.One user get his session hang, so when we try to force close it we get the message "Waiting for system event notification service" and the user sessions never close.It is happenig every morning wince we put the second XenApp6 server on our new farm. We are using MS Communicator 2007 R2, but we have applied the last hotfixes and patches in the server and client side: We don't have any NIC Teaming actived and we have installed McAfee Virusscan 8.7 in one server, and no antivirus in the other to test it, and we are having the same issue in both of them. Today we had the problem again, and this time, we had also a Com+ - event in our logs. The Com+ - event doesn't appear, but I don't wait for hours to reboot my server. The only thing that helps me a bit, is NOT logging off in a terminal session, but just close it. It happens every two or three days and I can't find a situation in which it always happens. I could not stop the SENS-service (even not with the taskkill-command). I tried the workaround from "rmoat", but I did not succeed to restart my server regularly. When I tried to logoff (in my terminal session), we got the "Please wait for the system event notification service". The server hung on this action (the computer nor network had problems, I could ping etc.). Could it be network-related? Today, I tried to reach a computer on my network (within a terminal session).

There is always a COM+ event notification a few hours before the total system locks. It has occurred 4 or 5 times since we started this. It looks like an issue occurs when one of the users logs off. In the Terminal Services connection manager, all users, even those with disconnected sessions will still be displayed. The only way to reset the system is a hard reboot. The 2008 physical server will also hang at the please wait for the system Event Notification service message upon logging off. Please contact Microsoft Product Support Services to report this error. HRESULT was 80070005 from line 147 of d:\longhorn\com\complus\src\events\tier2\security.cpp.

The COM+ Event System detected a bad return code during its internal processing. This following System Event occurs several hours prior to the "please wait for the system Event Notification service" message hanging the computer. This message freezes the client's computer as well as prohibits any other users from logging into Server 2008 RDC. Please wait for the system Event Notification service message displays intermittently on a Remote Desktop client upon logging off.
