The amount of PC's running Ultimate does not matter, what matters is if your
server can support the work load of PC's joining the Domain. Windows Vista
Ultimate is a retail version of the OS that only has 1 license per copy.
Licensing of the server also must be taking into account, if you have a
Server or bought a copy of Windows Server, the amount of CALs (Client Access
Licenses) should specify how many client machines or devices can access the
server.
