There's a few other basic items that you could check:

-TCP/IP connections are disabled by default
-check all port numbers are the same
-confirm that the SQL Server is actually running
-double check user names and passwords. You could check that SQL Server is set to mixed authentication. The driver from Microsoft can not handle Windows integrated authentication (there's third party drivers available that can). To do this, open Enteprrise Manager, right click on the server/properties, and select SQL Server and Windows Authentication in the security tab. Then create an SQL server login account.
-have you installed the SQL Server 2000 Service Pack (it solves a lot of SQL Server problems)?
-check http://support.microsoft.com/default.aspx?scid=kb;en-us;313178
