Value: Max users allowed
This may be key Microsoft uses to prevent workstations from servicing more than 10 simultaneous users. Max setting is ffffffff. My servers would all support this many simultaneous users (sure). In any case, if you have a workstation and try to get it to run like a server by twiddling with this value, I can not guarantee the results. It certainly violates your sw license and I suspect that there are other keys involved anyway.
