website cannot be started another website may be using the same port

Question

Trying to set up a default website in IIS. When trying to start the website I get the error message: "website cannot be started another website may be using the same port."

I don't see any other bindings on port 80 in IIS. Is there a way to determine what else might be using the port on the machine?

Thanks

Ran across an issue like this when I was setting up a new web site on port 80. Of course, the Default Web Site instance is also on port 80, and conflicts. I thought I solved this by going to "Edit Bindings" and changing the "Default Web Site's" port to 81 and leaving my new site on 80. I still could not start my new site.

I had to delete and re-create my new web site, then I could start it.

It's like it still thought "Default Web Site" was on 80, even though it wasn't. Even an iisreset, a recycle of my new site's app pool and web site all did not work. Maybe if I had restarted the site/app pool of the "Default Web Site", maybe that would've worked, too, but didn't try it - just deleted/re-created my new site. But that was enough to break through the "Default Web Site" keeping a hold of that port!
