Go to a command prompt and run:

netstat -a -n -p tcp -b

This will show all services running, protocal used, local and foreign address, state and PID (process identifier).

You can also use the following process outlined by Microsoft KB Article# 281336:(https://technet.microsoft.com/en-us/library/bb490947.aspx)

To determine which IP/Port is being used by a given program, use the following command:

NETSTAT -p tcp -ano 

The Netstat.exe utility has a new switch, the -o switch, that can display the process identifier (ID) that is associated with each connection. This information can be used to determine which process (program) listens on a given port. For example, the netstat -ano command can produce the following output:

Proto Local Address Foreign Address State PID

TCP Listening 888

If you use Task Manager, you can match the process ID that is listed to a process name (program). This feature enables you to find the specific port that a program currently uses. Because this specific port is in use already by a program, another program is prevented from using that same port.

  1. Launch Task Manager, click 'Start', then 'Run', and enter TASKMGR.EXE.
  2. Go to the PROCESSES tab. If you do not see a PID column, click VIEW, SELECT COLUMNS, and then click to select the PID check box.
  3. Click the column header that is labeled "PID" to sort the process by their PIDs. You should be able to easily find the process ID and match it to the program that is listed in Task Manager.

If you know that your Titan Server will be listening on port 21 (or port 22 for SFTP), you can further focus the output by using 'findstr', such as

netstat -p tcp -ano | findstr :21

This will search the netstat output for any entry that is using port 21. You can specify :22 instead of :21 to find services listening on port 22.
