Windows 2003 Small Business Server - Shutting Off

I have a crazy issue and want to see if anone can help me out here. I just purchased a server with Windows 2003 Small Business Server installed - after about 1 hour the thing shuts down (I have not seen it happen so I dont know if it just shuts off or powers itself down.)

I have gone under my power settings and told the hard disk and monitor to NEVER turn off - So its not a hibernation issue.

I have called support from where I purchased my server and was told it was a Domain Controller issue in Small Business Server. That if one was not configured that windows would shut off after a certain amount of time.

Has anyone heard of this? Because now I am stuck with a web server that decides it wants to shut off every hour.

PLEASE HELP!
