In order to replace the main hard disk in our server, I transferred the content of my C: drive on our server to a mirrored partition on another drive and then broke the mirror. Windows automatically assigned the mirrored partition the drive letter D:. I removed the original C: drive and jumpered the replacement drive as the master and rebooted. Since then, I've had nothing but trouble. I finally got it to let me log in by using little registry tweaks across the network. I've tried going into the "mounted devices" section of the registry and renamed the key from \DosDevices\D: to \DosDevices\C: several times, but the change doesn't survive a reboot. I close regedit and re-open it and the change is still there. I reboot the computer and it has changed it back to D:. I'm running out of possibilities short of reinstallation, which I'm trying to avoid. HELP!
