Hi, when trying to rename my computer at work  I accidentally chnaged my membership from domain to workgroup.  I now can't log on -- I've tried logging in with admin, guest, ect.. with no luck.  I am our sole IT guy, so I have access to every computer including or server station.  Is there any way I can get back in?  Help is much appreciated....

Try Administrator with no password as that is the default on XP for most OEM's.

You need to rejoin the domain. Right click on My Computer, properties, computer name tab, click "Change", type computer name and domain credentials. If all goes well you'll get a "Welcome to xyz domain". If not, there's some settings on the DC server you'll need to set to allow the user to rejoin the domain, but that I'm not sure about.

You'd need to logon as the administrator on the machine. If you can't, google around for recovering the administrator password, there's a few ways.

You can download software to reset the local admin password


That page will give you some information about reseting the password and what tools are available.

Oh the other thing to try is login as "Owner" with no password.

Some systems I've had, the OEM made the one and only user on the computer named "Owner".

If you need to reset the password use http://home.eunet.no/pnordahl/ntpasswd/
