Hi, Last night my NT server rebooted due to a power outage, and when I tried to restart it I got the following error: Windows NT could not start because the following file is missing or corrupt <winnt root>\system32\ntoskrnl.exe Please re-install a copy of the above file. So how can I reinstall that file without having to reinstall the entire OS and losing everything? Can I boot into DOS somehow or something to just replace this one file? Thanks alot.
