Enable remote connections for SQL Server Express 2012

Short Answer

• Check Firewall
• Check Service is Running
• Check TCP/IP is Enabled
• Check SQL Server Properties "Allow Remote Connections"
• Check if the SQL Server is on a restricted subnet

Then Run these if Those Do not Resolve

• Right-click on TCP/IP and select Properties.
• Verify that, under IP2, the IP Address is set to the computer's IP address on the local subnet.
• Scroll down to IPAll.
• Make sure that TCP Dynamic Ports is blank.
• Make sure that TCP Port is set to 1433.
• If you have a named instance then you must have the SQL Server Browser Service enabled
• The browser service runs on port UDP 1434 and this must be allowed through your firewall

Hail Mary Pass if this is Still not Resolved

• Go to the client machine, and run cliconfg.exe If named pipes is listed first, demote it, and promote TCP/IP.
• check if the firewall is blocking the named pipes port, which usually is 445
