There have been several technical articles about how the NT4 Workstation kernel is identical to the Server version. The article that I'm thinking of described how a certain registry entry controlled what mode the machine ran in. NT3.5 allowed this to change, but NT4 has some process running to reset it back. The article described how they patched something or other to stop the watcher process/thread/whatever and change it, and reboot, and a NT4 Workstation becomes a server, and benchmarks just like a server, etc. Hmm.. Lemmesee... The tech details: http://software.ora.com/news/ms_internet_andrews.html The collection of information about other anti-competitive things M$ have done with NT4: http://software.ora.com/news/ms_internet_frame.html BTW, There are apparently three values.. WinNT, ServerNT and ``LanmanNT''.. Hmm.. The last one, I wonder what that is? > M Cheers, -Peter
