User Change Script for Logon

We use several Windows 2000 Pro workstations  on a domain. We, the go-fors and do-its do not have the user domain passwords so we use a local administrator logon to update and maintain the machines.

When we log out, the user of the machine then finds our user info, administrator on local, in the logon box. They of course can't even begin to figure out how to logon. Some users seem unable to learn to type their user name in the box, their password and then to change to the domain logon--even after several "trainings."

Anyways, is it possible to use some kind of script or other method to switch the logon screen to the assigned person's user info from the default last logged on info?

Thanks in advanced.
