Using Remote Desktop Connection (from a laptop), I can connect to my desktop system and reach the Log On to Windows dialog. When I enter my account info and attempt to log on, the desktop system immediately power cycles. It doesn't go through any shutdown process, so I would guess some severe system error is causing it to reboot. Has anyone seen something like this before?
EDIT: The above behavior occurs when I'm logged into the same account. I tried logging out (on the desktop machine) before connecting and the desktop system froze instead of power cycling.
