servers

Is it possible to link to an SQL 2005 server db from a SQL 2000 server? Is there a driver for this?

Sure you can. Just open Enterprise Manager and locate your SQL 2000 instance-> go to Security->Linked Servers->Add Linked Server->Choose Server Type as SQL Server->switch to Security tab and configure proper security information to login to the SQL2005.
