MDM.EXE

Not sure where this should be posted.

I have Citrix Servers (4.0) running under Windows 2003 SP1. Among its
applications are Outlook2003. It appears that whenever Outlook is open,
MDM.EXE is also open. On one server yesterday, MDM.EXE was using 50% of the
CPU causing response time problems from the server. I can't find anything
that would cause this, and it doesn't appear that debugging is enabled on the
client. It also does not seem this affects all users, because I use the same
application and servers, and I only show as having OUTLOOK.EXE open, and not
MDM.EXE.

Does anyone have any ideas, or is there a better place to post this
question?
