If you're using Windows 2003, this happens when the IIS Web Services Extensions are not enabled. Open the IIS manager, select the Web Service Extensions node, then select ASP.NET v1.1.4322 and click the Allow button. Do the same for the FrontPage Server Extensions 2002. Note that both are disabled by default in this OS, unlike Windows 2000.
My question is perhaps very basic, but I'm new to programming. Where can I find IIS Manager (I have installed IIS already but can't find this function.) Thank you.
It's in Start -> All Programs -> Administrative Tools -> Internet Information Services.
