[dba-SQLServer] Cross-Posted: Windows 2003 Server

I realize that this question is slightly off-topic, but it DOES concern
my database server, which is running Win2K Advanced Server (for multiple
processors).

I just got Windows 2003 Server, whose installation program immediately
told me that it does not support multiple servers. Did I get the wrong
version? Or did MS stop supporting multiple servers? If the former, what
is the exact name of the product I need? (I searched some MS sites and
got no satisfactory answer.)

In short, it sounds like an upgrade is going to result in a downgrade.
Am I missing something?

TIA, and I hope this isn't too off-topic.
