this is very old thread (2003) for a problem I was experiencing on an old version of Adminstudio (5.x or maybe 6.0 - prior to VP1) on an old version of Windows XP (pre-SP2).
If memory serves me, I believe the problem did not occur after we upgraded to Adminstudio 6 VP1.
But can not swear to the resolution. All I can suggest is that all software is up-to-date (Windows OS, Adminstudio and h/w bios and firmware).
Sorry for not having more definitive answer - like I said, it's been a while and alot has happened between now and then, least of which my job role is different (from: Packaging/Adminstudio) to: Distribution(SMS/SCCM).
Pete.
