If you’re like me, communicating with others via Skype is as essential to daily living as breathing. But when it comes to running Skype on your dev machine, you need to make a few adjustments. By default, Skype will grab ports 80 and 443, which are used by IIS. So if you need to work on an ASP.Net web app using HTTP, you’d better watch out for this one.
If you want to keep Skype running and not have it grab these ports, just change the connection settings for Skype.
