Unable to start debugging on the web server.The web server is not configured correctly.

Setting up a DNN source project can be easy and difficult at the same time. Since this is an open source product code files have been modified by more than 1 DNN developer.

Recently I tried installing a source version on DNN 04.09.04. It was pretty simple and it worked like a charm, the problem started when I installed the source version (01.00.05) of the active directory module. I included it successfully in the project and hit the F5 button of the VS 2005 only to know that I received an error “Unable to start debugging on the web server.The web server is not configured correctly.”

Here’s what helped me fix the problem -

1. Right click the DotNetNuke.Authentication.ActiveDirectory.VS2005 and select the “Properties” option
2. Select the “WEB” tab of the project properties
3. In the “Servers” option incase “Use IIS Web server” option is selected, ensure that the project URL is the correct one, also ensure that the “Override application root URL” is the correct one.
4. Click the Save button from the toolbar.

Now just hit F5 and the application should run fine.
