A 'workgroup' is simply a logical grouping of computers.  On a network, only a single workgroup is needed.  If all of your computers are not in the same workgroup, they may not be able to see each other correctly.  Just make one up and stick to it. Keep it simple and easy to remember.

Each computer should get the SAME WORKGROUP name and a DIFFERENT computer name. Again, keep all names simple and easy to remember.

Fun Network Naming Examples  Workgroup: Atom Computers: Neutrino, Quark, Electron, Proton, Neutron, etc... Workgroup: Sol Computers: Earth, Mars, Venus, Jupiter, Saturn, etc...  Workgroup: Milkeyway Computers: Sirus, Centauri, Vega, Deneb, Canopus, Proxima, Rigil, etc...
