try disconnecting your cdroms , boot w2k without them ,shut down w2k .attach one of the cds again , and bootup w2k with one cdrom ,if it works repeat the procedure .
Or go to cp ad new hardware cdrom .I one got the same problem after uninstalling direct cd ,and easy cd creator in w2k .
making an img of a perfect working w2k with a goor program is always a remedy to a lot of needless annoyance .
