win2k doent recognise games CD

Archived from groups: microsoft.public.games.discussion (More info?)

When starting Flight Sim 2004 or Doom 3 (not tried other
games) Windows keeps requesting the original disk be
placed in the drive even when it is. This problem only
occurs when logged in above GUEST (e.g. Administrator).
When logged in as guest it works fine.

I understand there is a similar problem with winXP (but
the other way around) and there is a patch to fix it.

Anyone had a similar problem and is there a fix for it. Or
am I overlooking something obvious in the settings.
