This is really easy with SQL Server 7.0. It added linked servers that support the kind of functionality that you're asking for.

For 6.5 you'll have to do some work. You can call a remote-stored procedure to query the data on one server and stuff it into a temporary table. Then join that table with the other "half" of the query. Lookup remote stored procedures and INSERT w/ EXECUTE in the BOL.
