Force close an open port in Windows Server 2003

Question

On a server running Windows Server 2003 I killed the TS-service (specifically the svchost.exe which belongs to terminal services).

The service is not running anymore but the server is still listening on port 3306 (as is seen by running netstat -a).

How can I force this port closed?

Solution

This rule has enough information to make a port rule on the WS2K8 system. Within netsh, this rule would be entered as:

netsh advfirewall firewall add rule name="3306" protocol=TCP dir=in localport=3306 action=block

Thank you. I just want to close it one time so that I can start the TS-Service. Your solution seems to block it forever.

Sounds good, but TS isn't restartable in 2003. Wonder why killing the service was necessary... (wonder what the real-real problem is)

Yeah, normally it's MySQL that uses 3306 by default.
