Ok, this sounds weird and it is. I believe I had a corrupted DP server that wasn't properly responding to updates from the main Site Server.
Anyway, I have the client deployed to a test lab, my 3 SCCM site servers and the stand alone SQL box. In the last few days, 2 of the servers have been corrupt. The main Site Server Management Point and the SQL box have randomly booted to the SCCM 2012 copy of WinPE. All that is on the screen is the Dos box with a command prompt and the SCCM 2012 background.
I've confirmed that the "C" drive is intact and all files are still on it, but the servers continue to boot to WinPE on each reboot, not to their original Server 2008.
So my question first is, how do I remove the Windows PE boot from my C drives and get them back on line?
