How about this, would it work?
1 XP server and domain with 100 XP work stations. All with the programs that have been working and doing the job they have been doing for years. No Internet connection. 1 Windows 7 computer for Internet use that is Networked to the XP server. After the XP cut off the XP domain could still work as it has always done. My understanding is that workstation don't need Internet access to do their/there job. After reading many reports on Windows 8 and the new Windows Office; why would anybody go down that road? It's obvious I know little about servers and domains. If this happens would XP in a domain like this be counted in the total tally? 1 Server and 100 Workstations. Its just a idea of mine. With 90% plus of market share Windows only competition is Windows.

well XP can not be domain controler you need server os for that for example server 2003..
but I still know companies that uses windows 2000 server and workstations, even thought ms no longer supports that os
