Yes it simply shut down. No warning. I did check the Event Viewer. It only shows the machine went down. Then a few minutes later you see all the services starting up. No reason for the shut down.<br />
<br />
Thanks.

I was trying to join a admin on his RDP session. I am also an admin. The Server 2008 R2 Standard box immediately rebooted.<br />
<br />
I was told the two administrators should not share a session on a server. <br />
&nbsp;Could that have caused the reboot? <br />
If so why?<br />
<br />
Thanks.
