Ok, the xcopy drive will never work... here's why... You gotta reload that puppy... make an image of your good server and reimage the bad server, use either norton Ghost, or PowerQuest Drive Image. Your boot sector is blank... Xcopy will NOT re-write your boot sector. Another thing, If you can slave it and save any unique data, do it now before it's too late. Norton Ghost will NOT run on NT server, but there is a way around that... run it on a 9x box or an NT wks, and slave the server, make the image, slave the bad server, image the drive. Done, server should be fine after that.(personally I'd look at both programs and decide which will go further in the long run for you before you purchase.
Good Luck,
