Change PC from Domain to Workgroup steps to take XP Professional

Ok, first I recomend that you change the default administrator's account password. Because once the computer is out of the domain, you can not use domain users in that computer.

Then with the domain user give permissions to the local administrators group to the user profile directory (should be c:\documents and settings\username). Last step to be sure that you will access data information in the users profile.

Then only you have to enter Computer properties. You can press <Windows> + <Pause> or Rigth click in My computer and select properties. In tab computer name, select radio button workgroup and enter the name of the workgroup, could be home, office, or any other. Press ok until computer ask to restart and then restart it.

Once restart, you have to enter with a local account, administrator or any other, but maybe you won't can enter with domain accounts.

He said the domain is no longer available. He won't be able to make half those changes

I the domain is unavailable Then reset the local admin password and remove from domain by right clicking my computer, properties, computer name, change. Switch from domain to workgroup and type the name of the workgroup. You should be prompted for a username and password.

Even when the domain is not available, the PC maintain a cache for users logged on this computer for many days, 30 I think, but I'm not sure. That's why He can log on to the computer even when the domain is not available. Then He can make this changes.

Sorry, my mistake. I thought you were having him change stuff in active directory for a domain that doesn't exist anymore
