When you remove a computer from a domain there are a few steps you should take to ensure that its GPO settings are removed properly as well.

There are various different reasons why you might want to remove a computer from a domain within your network. Regardless of the reason, you have to be careful that you take notice of group policy being applied to the computer in order to prevent “orphaned” GPO’s.

An orphaned GPO is the result of what happens when you remove a computer from a domain without removing its applied Group Policy Objects. In order to prevent this from happening, it is a good idea to first move the computer in Active Directory into an OU that has no GPO’s applied to it before removing it from the domain completely. It is also a good idea to make sure that this OU is blocking policy inheritance from OU’s above it. Doing this will completely ensure that you all group policy settings are removed from the computer in question.
