Shutdown But Don't Power Off My Servers!

I manage HP ProLiant servers and we've been having power outages. What would happen is that a couple of servers wouldn't power on automatically, even though the BIOS setting was to restart when power was restored.

The offender was a Windows 2003 server that would get a signal to shutdown (i.e. kill all Windows processes) but would ALSO turn off the power to server. What I wanted was the power to remain on for the server and to let the UPS remove the power so that when building power is restored, the server will turn back on.

I found the solution at www.annoyances.org: You could try changing the following registry value. Go to Start-> Run ->regedit. Browse to the following key and change the value shown. [HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon] "PowerDownAfterShutdown"="0"
