I have had an Error 'SQL Server does not exist or access denied.' when trying to start Network edition. What does this mean?

This error indicates that HandicapMaster is unable to communicate with the SQL Server.

Please check that the network between the client PC and the SQL server is operating correctly. If it is then this may mean that a firewall is preventing communication between the client PC and the SQL server.

If you have a firewall on the client PC you may also need to configure it to allow you to communicate with the PC where the SQL server is located. Please discuss this with your firewall administrator.
