I have a Windows 2008 R2 server, and every time someone logs in via Remote Desktop, or on the console, it crashes. The only way to get it back is to power it off, and back on.
It will continue to ping, but, file sharing, and all network services (it is my Exchange server!) stops. It never fully logs in, but stops at "Welcome."
We cannot trace it to any change.
It is a Virtual server on Vmware. There are no events in the event log that point to why it crashes.
Any ideas on how to troubleshoot?
