I already have a program running on port 80. Another program that I want to use, also runs on port 80. Is there another alternative port that can be used so that they can be run at the same time?

What programs? I commonly see this with skype and apache. If that's what your situation is, start apache first, then skype. – Force Flow Dec 1 '10 at 3:38

you can run a netstat command from a command line - try something like

netstat -an |find /i "listening"

Port 8080 is an official alternative port to port 80. So if it is not already in use, it would be a good one to use.

http-alt    8080/tcp    HTTP Alternate (see port 80)
http-alt    8080/udp    HTTP Alternate (see port 80)

To see what ports are currently in use, I would use the netstat -a command to look for connections in the LISTENING state

If the app (and the client/server it connects to) allows you to change the port you are good, else you might need to try some kind of port forwarding.

Great, because they both do actually. But now, how do I find out what other ports are available and which ones I can use? – Amy Dec 1 '10 at 1:19
If you randomly choose a port, you will most likely get an open. Did you try port 8080? thats another default for http traffic, which should like what you are doing – thegreyspot Dec 1 '10 at 2:00
