Exactly which service-pack level of SQL 2000 do you have? You can view
this on the first line of
C:\Program Files\Microsoft SQL Server\MSSQL\LOG\ERRORLOG
(if this is the instance directory for SQL 2000.)

I believe you need at least SP3 (8.00.760 to run in parallel with SQL 2005.)

Another thing to try is to open the Server and Client Network Utilities of
SQL 2000, and make sure that both use TCP/IP. For local connections,
shared memory is the default, but if it for some reason does not work, you
can try TCP/IP.
