Hi,
That would depend on what the roles of the computer are and if the computer
is a member of a domain. For example, it would not be a good idea if the
computer is a domain controller. If the computer is a member of a domain, I
would make the computer a member of a workgroup first so that you can more
easily add it back to the domain. I would recommend a system state backup
before trying this in case things go wrong. Here are some related articles:
