I added my boss' username and password to my server at work so he could use the shared printer. I wanted to remain the only person who can actually login to that machine to use it, so I set the security policy to deny local logon to "users" (I login w/ administrator).

Anyway, while I was doing that, the menu hung for a bit and crashed. Went back in and the setting stuck, so I thought all was well and rebooted. When I attempted to login, the system very nicely informed me that Administrator no longer has the ability to logon locally! D'oh!

Is there a way to fix this? I have access to WinTernals, but have never used it; could it help?

?? Connect to machine over the network and fix it. Should be able to connect fine over MMC.

Ok, so how exactly do I do that? I can open MMC and map the drive of the computer I want to fix. Upon attempting to open the remote .MSC file, it just opens up the policy for the machine I'm currently using.

Nevermind, fixed it with NTrights.exe
