Adding local user to local administrator group

[Scott]

I've just upgraded our NT domain to Windows 2003 Server
Active Directory, still in mixed mode.

I just built a new W2K workstation box for a new
employee. We have always added the domain user
(DOMAIN\newuser) to the local admin group
(NEWUSERPC\administrators) of their own PC so they can
install and run updates.

Now, I've logged in as the local admin on the PC, tried to
add the user to the Admin group and it allows me to pick
the new domain and askes for an admin user that has
permissions to the domain and I enter my user name and
password and it connects to the domain and shows me all
the domain users. However, when I select the new users
(DOMAIN\newuser) and click on Check Names, it says the
says the domain is non-existant or cannot be reached.

Any way to get the domain user added to the local PC's
admin group so they can install and run Windows Update
themselves?
