windows 2000 or advanced 2000 o.s.

Hi,
I’m going to install a new o.s. on system w/the following: 4 processors, xeon 450’s, alittle over 3 gigs of ram, 12 — 9 gig hard drives… This will be a test database (production) server….
I’m debating wether to install windows 2000 server or windows 2000 advanced server.. I know I meet the requirements for the 2000 server.. Should there be any other reason why I should install windows 2000 advanced server w/the above spec’s..

Thank You
