W2K has lost them...

Problem: the system has 2 hard disks and 2 CDROMS (DVD and Pioneer DVD-RW). When i installed win 2K 2 weeks ago it was fine. the problem now is no CDROMS are seen in windows.
they are seen in the IDE detection on startup but not in W2K.
i have tried them on the primaryIDE - same problem
replaced the secondary IDE cable - same problem
tried the drives in another machine - they work

any ideas?
ps: i know there is a post about this already but i havent installed any W2K service packs so the 'known issues' shouldnt apply?
