I have a Windows 2000 Operating System with 4 processor, out of which I'm planning to use only one Processor for the SQL Server and leave the rest of the three processor for the OS.
My question is that do I need to buy the license for all the 4 processors or I can do with the only 1 that will be used for running the SQL?
My understanding based on ms licensing documentation you would need licenses for all processors that the OS uses (not the server software) but I would consult with ms sales to confirm. How many users will you have using sql server ? The per processor license may not be the most economical way to go.
