Any processor limitation in NT, under 32 processors, is purely a licensing issue. I believe the retail versions of NT Server and NT Workstation are both licensed up to some number of processors, and acquiring a license for a higher number of processors requires purchasing the software through an OEM vendor. The idea behind this is that machines with a large number of processors would serve customers best by having the OEM support the machine as a whole -- hardware and OS. This is NOT the official word Microsoft -- I'm just an employee. Here is a clip from http://www.microsoft.com/syspro/technet/boes/winnt/nt351/tech3000.htm : "Multiprocessor Versions Available from Hardware Vendors" "As mentioned, Windows NT Server will run on hardware with as many as 32 processors. It is important to note that the retail version of Windows NT Server is licensed to run on machines with up to four processors. This is not a limitation of the scalability of Windows NT Server-it is a licensing restriction of the retail package. Versions of Windows NT Server that run on more than four processors are available from OEMs who offer multiprocessor hardware systems (up to 32 processors). Windows NT Server is included as part of the base system on these larger machines and is fully supported by OEMs who work with Microsoft." I can't find the similar text for NT Workstation, but it's there. -- arlie > -----Original Message----- > From: Narvi [SMTP:narvi@haldjas.folklore.ee] > Sent: Monday, April 28, 1997 2:05 AM > To: Michael L.
