user is administrator, but cannot update windows, etc.

[boryan]

Have XP Pro, SP2 running on Windows 2003 domain. Have user set as administrator of their own computer and as a regular user on domain. But every time try to do anything as administrator of their computer, like update Windows, or Office, or just about anything, it says they need administrative rights. I've deleted user, added her back in, adding her to administrator group on her own PC. Now, when she actually logs on, of course, she's logging onto the domain, not the individual PC,but that can't make any difference. Most all business users are logged onto a domain, not their individual account on their PC. Other users are administrators of their individual machines, log onto the domain, and are able to get Windows automatic updates..... Checked for viruses, spyware, etc., nothing there. I'm obviously not making these people administrators on the network/domain itself. So what's up with this? Any ideas? Some of this supposed security from Microsoft is getting onerous and burdensome.
