I doubt it's network related since the services are running locally on the SQL box....but what protocol is the service using to access SQL? Is it using named pipes since it's running locally or TCP/IP?
Is the error you're receiving thrown by some internal mechanism that you've included int he middleware, or is it showing up in the Event Viewer/SQL Server logs?
