SQL Server is started but didn't listen on any port
What made my SQL server listen for TCP connections on port 1433 was the following...


Configuration Tools / SQL Server Configuration Manager
click the instance name in SQL Server Network Configuration
enable TCP communication
Right-click the TCP communication entry, choose Properties
Click the IP addresses tab
Enable all non-VMnet IP addresses and enter 1433 in the Port entry for "IPAll".
Restart the SQL Server on SQL Server Services tab 
Check your configuration with netstat -an: 

C:\&gt;netstat -an | find "1433"
  TCP    0.0.0.0:1433           0.0.0.0:0              LISTENING
  TCP    [::]:1433              [::]:0                 LISTENING
