Convert to Workstation from Server

[Halfnote2]

A friend was given a computer and it has 2000 server on it. SHe did not get any any

softwear cds with it. I have tried to install antivirus on it and they all say at they

can not install on a server. This computer will not be connected to any network.

So is it possible to change the server status to a stand alone status non-server.
