SQL Server is started but didn't listen on any port I newly installed SQL Server 2012. No database created yet. And I can open the Management Studio with sa/password. The Binn\sqlservr.exe is started as a service and I can see it started in the service list. However, it didn't listening the 1433 port, or even, not listening any port by default, as I checked as below: 

tasklist|find /I "sql"


I got: 

sqlservr.exe                  5668 Services                   0     40,112 K


in which 5668 I think is the PID. And then to get PID = "5668" is listening to which port:

netstat -ano | find /I "5668"


but I got nothing except blank. On the other hand, after searching posts in this site, I double-checked my SQL Server's configuration: start->All Programs -> Microsoft SQL Server 2012 -> Configuration Tools -> SQL Server Configuration Manager-> SQL Server SQL Native Client 11.0 Configuration -> Client Protocols -> TCP/IP ->Default Port 1433. There're 3 services, SQL Server(MyInstanceName), SQL Server Agent(MyInstanceName) and SQL Server Browser. The last two is stopped. 

SQL Server Configuration Manager-> SQL Server Network Configuration->Protocols for MyInstanceName -> TCP/IP is disabled by default, after I enabled it and restart the service and repeat the netstat -ano | find /I "newPIDNum" command I found the 

TCP    0.0.0.0:52395          0.0.0.0:0              LISTENING  5668(newPIDNum)   


Why 52395 instead of 1433? And I failed to create the DSN using Windows ODBC Data Source administrator which returns me an error: specified SQL server not found. 
Any help for me? Thanks.
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
