  SQL Server Tips by Gama and Naughter


 

Use 0 as the port number

 

SQL Server will use the first free port between 1024 and 5000, instead of 1433 (TCP access to the database, usually remote). However, 1434 (UDP, to access and browse named instances) will not change. Let us suppose the first available port was 1027, SQL Server will take this port and used it there after. If many other programs are listening on ports, then the port number SQL Server will use will be the first one

it finds available. You can list the ports active on your machine by

using the "netstat -a" command line.

 

Select a port from 1024 to 5000

 

SQL Server will listen to any port selected, 1434 will not change. Obviously, no other application should use the port and the firewall should protect it. If the server is not always running, the port will be free and there is the possibility that other application might start using that port.
