First, troubleshoot basic connectivity. Can your application server ping
the database host server by IP address and by name. Try it again using the
virtual server IP and name. Next, connect to the SQL instance using one of
the client tools (Enterprise Manager, Query Analyzer). You may need to
upgrade the MDAC version on your application server. Older versions are not
instance aware.
