I have heard that you can use Windows 2000 professional workstation in a workgroup much like a server. My aim is to centralize the location of shared files in a workgroup of 5 computers in one location, one PC that everyone can have access to with a security/permissions-type structure. In this situation, this would be more cost effective than purchasing the server application. How do I set up this type of workstation workgroup network with one PC serving as the main file repository and provide security access just using Windows 2000 Professional workstation?
