I change my 2003 server from domain to work group and restarted the machine and now i cannot login. Do any body know of any solution other than reinstalling the OS?

When you originally installed that server you had to have some local account and password that is a local administrator. Without it, I believe you're out of luck. This "IT Management Planning and Technology" forum isn't the right place for this kind of question, anyway. I'll move this thread to a better location. Maybe someone there has some additional options for you. -Kevin Kevin Remde US IT Evangelism - Microsoft Corporation http://blogs.technet.com/kevinremde

Aside from Kevin's suggestion, try this if you cant remember the administrator's password. http://www.petri.co.il/forgot_administrator_password.htm Also try administrator as the user name and blank password, you might get lucky! Some manufacturer's install utilities default to a blank password. You never know! CheersMiguel Fra / Falcon ITS Computer & Network Support, Miami, FL Visit our Knowledgebase Sharepoint Site

Usually, we can reset Windows admin password in two traditional ways. The first is to change Windows password with another admin account; the second is to recover the previous password with the windows password reset disk that had been created before you forgot the password. Take Windows XP for example, At the Windows XP login prompt when the password is entered incorrectly click the reset button in the login failed window. Insert the password reset diskette into the computer and click Next. If the correct diskette Windows XP will open a window prompting for the new password you wish to use.
