Since you are using the .NET Framework 3.5 I will assume you are using Visual Studio 2008, and you say you are targeting IIS 5.1 for the production platform.

The local web server that is part of Visual Studio 2008 is based off of IIS 6/7 architecture, not IIS 5. So, to answer your question of what is different with IIS compared to the local web server... unfortunately, in this case, you are mixing apples and oranges.

Are you restricted to IIS 5.1?... ie client mandate or some other reason. If you are not, and you are developing with Visual Studio 2008 (.NET Framework 3.5) you really should be using IIS7 (or at least 6) as you would most likely not have this problem.

Again, IIS7 may not be an option for you.
