Missing cd-rom drives?

[ludi_f]

I have a little problem: after i install windows xp, cd-rom drives (even virtual cd-roms, if any) dissapear from my computer. This is even more strange because:

-it is not windows xp kit related (i used the same kit before and i didn't have such problems)

-it is not application related (i installed different applications and with the same result)

-it is not unattended related (it happend even with normal xp kit)

-it is not system related (same system)

Maybe it is about bios, i don't know.

I found out that there are more situations like this. I found a registry modification that will fix this, even a small vbs program. But what intrigues me is why is this happening? if you heve any ideea, please post it on this forum.

Thanks

I had this problem once or twice. Happened to me when I upgraded a NT4 workstation. Search your registry for UpperFilters/LowerFilters in the entries for your drives and backup/delete them. That *should* help.
