I came across this error after converting a 1.1 based Web Application (developed with VS2003) to a 2.0 based Web Application. Strangely though, when I chose to convert it to 3.5 instead the error never appears and I can access the project with no problems.

The URL being used to connect to IIS does exist and is available.

On Windows 2003 - This exception will occur if VS can not find the IIS virtual server specified in the Web Application Project file. In my case, I had renamed the web application (and changed the host header)

To resolve:
Open the Web Application Project .csproj file
At the bottom of the document locate
<ProjectExtensions>
<VisualStudio>
<FlavorProperties...>
<WebProjectProperties>
<IISUrl>your WebApp Project IIS server url</IISURL>

Ensure the value of <IISUrl> is the URL of the IIS virtual server mapped to the your Web App project root.

Just run VS.NET as Admin on Vista.

This occurred for us on our W2k3 build server.

Because this was just a build server, we have no need/desire for IIS to be installed.

In the Web properties page for the project, Uncheck the box that says 'Apply server settings to all users (store in project file)'. This will then remove the dependency on IIS for vanilla builds, but dev users can change their IIS location on a per-machine basis (which is probably correct for development anyway).
