I installed the latest version of the SEPM basic client (12.1.2100.2093) on my 2003 R2 server, which hosts our 2007 Exchange environmenet. SInce then, the server hangs on reboot/shutdown with a grey screen and mouse pointer. I can ping the machine, but cannot manage the machine at all. I have to force the server to shut down. I left it all night like this to see if it would resolve, but it just stays on the grey screen.
I removed SEPM client and the server now functions properly again.
There are no event logs pertaining to the issue that I can identify.
I cannot afford to keep reinsatlling this software and rebooting as this is a critical server in our enviornment. I am hoping to find some recommendations which I can try that will allow me minimal down time with this server.
