When ANY domain user tries to log into a particular Win2K workstation they recieve the following error message "The LocalPolicy of This System Does Not Permit You to Logon Interactively". Upon logging in with a LOCAL account I find a strange entry in the Admin Tools -> Local Security Policy -> Security Settings -> Local Policies -> User Rights Assignment -> Log on locally properties. And there is a column for "effective policy settings" which I have never seen before. Inside that column there is a greyed-out checked box for this new entry, which I ofcourse cannot uncheck. There is nothing in the "Deny Log on Locally" properties. Anyway, the only solution to the problem I've found is to remove the computer from the domain, and then re-join it. Unfortunately the symptom then re-appears the next day. And no domain user can log into that machine, receiving the above error message. The machine in question is a laptop and connects via VPN in the evenings. I have confirmed the unit to be virus-free. If anyone has any insight into this, it would be GREATLY appreciated. Thanks!
