I am running into never ending problems with granting admin privileges to a user.  After a full days work, I finally got samba to work as a PDC.

The problem now is that I cannot grant admin privileges on a particular user say eric in the USERS group.

For example when I log into a XP computer, some services are not available due to lack of admin rights.

DON'T grant root privaleges to your users, as you've seen it can cause hassles.

Your best bet is to make their domain user a LOCAL administrator/power user for their machine.

This has to be done on each workstation. A better way would be to find why they can't run certain stuff and change the permissions for that (eg security permissions for certain registry keys). This can be a pain but often possible to do remotely (NB regedit works nicely under wine).
