RE: Skype and Port 80

Here’s a good tip to remember if you are using Skype and doing web developement…

I was having trouble with my IIS on my local machine — namely, it wouldn’t start.  That’s not good, because I do a lot of ASP.NET development, etc.  Well, the reason it wouldn’t a start was “EventID 15: Cannot bind” something or other.   A poke around the Internet told me to check to see if there was another application bound to good old port 80.  A tool called ActivePorts told me that good ol’ Skype was blocking out Port 80, and not allowing IIS to start.  Interesting.  So I went to the Skype options, and then to the Connection tab, and found the interesting “Use Port 80 as an alternative for incoming connections”.  Bingo — disabled that “feature”, and IIS was back up and running.
