Mithrandir,

From the mouth of Microsoft:

"On Windows 2000, standard editions of SQL Server support up to four processors. Enterprise Editions support up to 32 processors (8 with Advanced Server and 32 on Data Center Server)." 

I suppose I should have clarified the part about SQL Standard Edition which supports up to 4 processors on Windows 2000 vs. SQL Server 2000 Enterprise Edition (which supports 8 processors on Advanced Server and 32 processors on Data Center Server).  Sorry about that.  The wording was unclear.  Please see the reference link at the bottom of the article to go to Microsoft's Pocket Consultant for SQL Server 2000 for further details.
