ODBC Fails SQL Authentication from client computer to a Named Instance in the server


When the ACCESSCONTROL database is attached to a named instance, the following error might occur when configuring the ODBC on a client system:
Microsoft SQL Server Native Client 10.0 : A network-related or instance-specific error has occurred while establishing a connection to SQL Server.
Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections.


Verify that the SQL Server Browser service is running on the server. This service provides SQL Server connection information to client computers.
