IIS 7 does not allow ports on Windows Vista

After clean installing Windows Vista, Visual Studio 2005 and Visual Studio 2008 on my work computer, I started having problems with using dynamic ports with ASP.NET.
When ASP.NET web applications are executed in VS 2005/2008, they may run on dynamic
ports on the local server, e.g. localhost:12345. This worked before the clean install,
but now I found myself being incorrectly redirected to www.localhost.com:12345.
After struggling with this, I eventually found a solution here. If you face the same problems as I did, I hope that it helps you out.
