Symantec Endpoint Protection Manager 12 has locked a port.

Symantec Endpoint Protection Manager 12 will not start the service. The issue is that port 8014 is in use. We have changed it to port 8015 and the service starts, however, all clients have 8014 as the communication port and the management server cannot communicate with them. We are unable to locate what is using port 8014.

This was running on another server and the customer moved it so anything that was pre existing in setup we were unaware of. This server also has Symantec Backup Exec 2012 installed.

We would like to get port 8014 unlocked and used by Protection Manager.

Try netstat -abn in the elevated command prompt (cmd.exe --> Run as Administrator). If the output of the command is too large then redirect the output to text file and then analyze the text file. E.g.

netstat -abn > C:\ports.txt

This would save the output to ports.txt file located in C:\

The results of the command show that the port is labeled as [System]?

Can you telnet to port 8014?

Yes, we are able to telnet. The port accepted a telnet session.

And what did you get in reply? I mean what application is been hosted on port 8014? IIS?

It connects to the port via telnet but there is no response. What I mean is that it opens the blank telnet window and does not time out like it would if the port was unreachable. This is the same with 8015 to which we had to change the port to in order to start the management service.
