I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Reboot into Directory Services Restore Mode, Safe Mode, or Safe Mode with Networking and log in using the DSRM password, re-enable the NIC and reboot normally.
