Unable to start debugging on the Web Server. Visual Studio 2008

Question

I am running visual studio 2008 on vista business 64-bit. I am getting the following exception when I try to debug against IIS.

"Unable to start debugging on the web server. The object identifier does not represent a valid object".

IIS and Visual Studio are on the same box.

I've tried adding Windows Authentication but no luck (my app requires forms authentication, fyi).

Any thoughts? I have a binding on the Web Site. The IIS app is a Web SIte not a virtual directly.

Thanks!

Answer 1

Go to IIS right click on your project go to Asp.Net tab change the version to your current verion you are using.

This problem comes when you are using a higher version and decided to switch to a lower version and vice versa changing to your version might solve the problem

Answer 2

You have switch on Windows Authentication in IIS

Answer 3

Is your pc and the webserver on the same Windows domain? If not, or there is a DMZ between your pc and the web server you could experience problems unless you've explicitly setup trust between the machines.
