Iis – What do you do in IIS if you get an error when trying to start your default web site and it says that it cannot be started because another web site may be using the same port

netstat -ab | find ":80 "

Notice the space after 80. The /b requires an elevated command prompt.

EDIT: After close inspection, piping netstat -ab into find with that search string does not display the executable that the -b switch retrieves. This is because -b displays the owning process on a new line. =( I fail. But at least the first half of the command will work. I just had to get all fancy with the find command. =)

Is the server sitting behind a firewall that only opens port 80, not 8080? That would be my first guess, but hard to know without knowing how the server is configured, where it sits etc.
