Ben, Have you tried from another workstation connecting to the c$ drive using the local system credentials. This is assuming that its not a DC. net use z: \\servername\c$ /user:%computername%\localadminacct
If this works and it should since its a network login not a local login, open the mmc and connect to the computer management on that machine. Go into local users and groups and remove authenticated users and interactive as users. This will make the administrator account effectively not a "USER" You should be able to log on locally afterwards. I know this worked for me on a 2k server. Not sure if it changes things for 2k3. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
