Error while trying to run project: Unable to start debugging on the web server. You do not have permissions to debug the server.
When looking for this error on google you get 274,000 hits, with this post we'll make it 274,001. ;)
I just got a new PC and was moving all my dev stuff over to the new machine when I got a support incedent and needed to replicate the problem and find a solution. So I fired up VS2003 (yes, this is a 1.1 web app) and it gave me the lovely error that you see in the title of this post. Then I searched google and found all these solutions that did nothing for me. Being a little bit perplexed I fired up IE and tried to go to the site and low and behold I had a whole host of web.config issues I had to sort out first. After doing so and making sure the site actually worked first, I tried to debug again, and it all worked like I expected. Moral of the story, make sure about the basics before your google for a problem. ;)
Hope this is helpful to other.
