I have a Windows Server 2003 machine (SP2) running Exchange 2003 SP2.
Overnight, with no updates of anykind taking place, the server started to hang.
What I have found is that when restarting the server, it hangs and does not get past the "Applying COmputer settings" screen.
The only way I was able to get the machine to boot was by disconnecting the LAN cable.
Once in, I noticed that the Exchange services are have not started - although set to Automatic. I changed these to Manual, and restarted and the server booted fine.
Now, when trying to start the services I start them in order of dependencies. But when I get to the Exchange Information Store the machine hangs and is not responsive.
The only way out is to do a hard shut down.
Anyone have any ideas?
