Stop reposting your question: bear in mind that it's a Sunday, and most of the western world is not working today. Continually reposting because you haven't had an answer is rude, and unnecessary. And if you continue to do it, I'm going to start considering it abusive behaviour...

Change the name of one of the PCs so it is unique.

Try using the ip address instead of a name, example SQL Server connection string:
Data Source=\SQLEXPRESS,1433;Initial Catalog=MnStores;Integrated Security=SSPI; User ID=pc1;Password=admin;

In SQL Server Configuration Manager->SQL Server Network Configuration->Protocols, check that named pipes and tcp/ip are enabled.

Check if your firewall is blocking the port.
