Windows Server 2000 Group Policy Lockout

I'm basically an idiot and was working on locking down a library's public computers this morning through group policy.

I was in a rush and was adding user groups to roll out the group policy and mistakingly applied the group policy to administrators.  Now, I'm sure you can assume what happened next. (I can't undo what I did on the server because I am locked out of any programs but the ones specified in the group policy)

Any help would be MUCH appreciated. It would be helpful if I had an answer other than reinstall, unless that is in fact the only way.

Hi
Depends to what degree you've locked yourself out really - could you give more information on which policies?. Some options are
Install adminpak from 2000 server disk on client pc, login with admin account and try use aduc snap-in, or try connect to the server's registry remotely from another client. Read these, be clear, and be careful with the registry though!

Well...  They're locked down enough that I would not be able to run regedit :(   Basically every possible user intervention has been blocked. No access to drives, can't install from optical drive, can only run specified programs (IE, Word, Excel, Powerpoint, Publisher)  I can get into specifics if you'd like but I think you get the idea.

I do however have ERD system commander so I could boot into a pseudo windows with that to access registry editor. I wouldn't think I'd have any restrictions there...

Thanks for the help, much appreciated

IF you can get into the registry it's your best shot I think. Group policy affects mostly registry based settings, if you can turn them off you should be able to get in. Other than that you're maybe looking at trying an Authoritative Restore of AD from the links below, but you'll need a good backup. Depends on how many DC's etc you have as to what problems you may face.  Have a good google for it, as there are many things to take into account depending on your environment.If you ARE faced with this, it's still better than a total rebuild (shudders at the thought - sorry it's not funny I know, just trying to lighten you up - but it won't kill you, the sun will still shine (unless you live in England where the rain will still rain), birds will sing and users invariably get over it -truly!).
