I have spent the last ~2 days trying to get brand new out of the box Dell Optiplex 755s working with RIS. I don't understand how I'm having more problems with this one system than I have with all others Dells I've used with RIS combined.
The problem, as it stands, is this.
I have the Optiplex 755 SATA set to "ATA" or "AHCI", neither matters. I download the image (A fresh one or an existing one with the appropriate drivers in the TEXTMODE folder) by PXE booting to RIS (WDS Legacy mode, its a W2k3 SP2 server). The image downloads perfectly, and then when the system reboots, it goes to the Windows logo and reboots after a few seconds. This happens both with a preexisting image I've updated and with a brand new image I just built on one of these machines. It reboots over and over. If I attempt safemode on the new image, the lockup will reliably occur on either cdrom.sys. I tried disabling the cdrom and it did nothing, I imagine its not cdrom.sys causing this but I suppose it could be.
I'm losing my mind here, and I'm facing Monday with a lab that was supposed to be up this week still down.
Any help would be greatly and truely appreciated. If I get any suggestions I will go in Saturday afternoon and try them out.
