Turn on the Windows service called "SQL Server Browser" and start the service

In Windows Firewall:
enable incoming port UDP 1434 (in case SQL Server Management Studio on machine A is connecting or a program on machine A is connecting)
enable incoming port TCP 1433 (in case there is a telnet connection)

In SQL Server Configuration Manager: enable TCP/IP protocol for port 1433

Make sure the service of sql server instance is running

and for connection string use . (dot) instead of PC-Name, dot denotes the current user

Server= .\SqlExpress; Initial Catalog=..........

where SqlExpress is your instance name (replace it accordingly)
