Adminstrator Account Permissions Problem

Archived from groups: microsoft.public.win2000.general (More info?)

I am having trouble completing some Windows Update pathces and also am unable
to uninstall a few appications. I receive an error stating that I do not
have aceess to some files and need to login with an adminstrators account.

I am not able to install a few programs also. Such as ACDsee (latest
version) and Macafee software. I get the same type of error message stating
that I need to be an adminstrator to perform the function.

I have checked everything I can think of and everything looks fine. I log on
as adminstrator, have adminstrator priveledges.

Any help would be very much appreciated.
