Help with internet ports

[ChrisMG187]

I'm trying to install a server but it says that my port 80 and port 443 are in use, how do i tell what ports are being used by which program?

Here's a list of common IP ports:

In Windows, you can use the 'netstat' command to view all active & listening ports (use 'netstat /?' for list of options).

port 80 i think is used for frontpage server extensions

Sorry - here's a better list:

Port 80 is HTTP, 443 is HTTPS.
