"Unexpected Error 0x8ffe2740 Occurred" Error Message When You Try to Start a Web Site

Mental note: Skype will grab port 80 if it starts up before the IIS Web Server leading me to "Unexpected Error 0x8ffe2740 Occurred."

Fix: Turn off "Use port 80 and 443 as alternatives for incoming connections within Skype's options.

Yeah - this is one of those fun ones that's easy to google once you already know the answer:
http://www.google.com/search?q=0x8ffe2740+port+80+iis+skype

Skype and IIS are in collusion on this one - Skype picks a crazy default (assuming it's okay to take over port 80) and IIS serves up a completely wacky error message. Would it be so hard to tell use which EXE is using port 80?

Brilliant.

I have had problems opening a solution in Visual Studio with the error 'the server is not running asp.net 1.1'.

I tried everybody's 'answers' to try and fix the problem and they haven't worked.

You have given me the simple solution!
