I have sleep set to NEVER everywhere I can find. Still, server will go to sleep (and I have to use Ctl-Alt-Del to re-start) after only a few unattended minutes. I've changed Screen Saver, Power Options - everything I can think of - still sleeps regularly. Any thoughts?

Put this on Serverfault? – Tom Juergens Oct 6 '10 at 19:25
Is server sleeping or hibernating? Have you checked Power settings in the BIOS? – Christopher Oct 6 '10 at 21:19
Sleeping (I believe) - I need to hit Ctl-Alt-Del and then re-login. I;ve looked in the BIOS, don't see anything related to sleep/suspend - is this something in particular I should look for? – user56351 Oct 8 '10 at 0:02

Try the following two commands, in order, from a command prompt:

powercfg -h on

powercfg -h off
