I use 2000 server in a small network and the machine is also my workstation. It recently started to freeze at various times for no reason and became increaingly flaky. I have run adware6, hijack this, Spybot and Sophos at regular interval, Sophos every night. The other day when I booted it up it came up with the following message and refuses to boot into 2000 server. "Registry cannot load the hive file SystemRoot/System32/config/Software" I have most of my files backed up, but the thought of having to rebuild the rest of it fills me with horror. I cannot get onto the hard drive all (it is a mirrored raid array). The emergency boot disk is missing, I have boot disks for PCs going back years, many of which have gone, but not the important one. If I put the 2000 server CD in it cannot see the raid disks but can see other disks in the machine. I have put another disk into the machine and installed Win 2000 in the hope it will allow me to see the other disks to no avail. What can I do to try to repair the damage.
