SYMPTOMS

Exchange 2000 Conferencing Server Web pages may stop responding when a Web client tries to gain access to them. The Exchange 2000 Conferencing processes do not show any CPU utilization in Task Manager. If you try to stop the Exchange 2000 Conferencing services, you may not be able to. The following error messages may be logged in the event log:

CAUSE

The default exception handler handled an access violation and permitted the service to continue running. This problem may occur if the thread that caused the access violation is a thread that must run for the Exchange 2000 Conferencing service (Xconfmgr.exe) to run. If this is such a thread, the service does not allow Web clients to connect and use the Exchange 2000 Conferencing Web pages.

An error occurs while Exchange 2000 Conferencing Server tries to process a meeting request with an exception record. If the meeting is not parsed correctly, an internal exception occurs, and the default error handler is called to log the error to Windows Event Viewer.

RESOLUTION

To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
