"Unable to start debugging on the web server. You do not have permission to debug the application. The URL for this project is in the Internet zone."

You may receive the error "Error while trying to run project: Unable to start debugging on the web server. You do not have permission to debug the application. The URL for this project is in the Internet zone. Click Help for more information."

This is one of the various errors that appear when you are debugging and may haunt you until you do the following fix:-

1. In the Internet Explorer, "Tools" Menu, select "Internet Options".

2. Switch to "Security" Tab.

3. Click on "Internet" (The Globe Icon. Its actually the default selected).

4. Click on "Custom Level" in the bottom.

5. Scroll down to find the "User Authentication" section.

6. Select "Automatic logon with current username and password".

7. Click "Ok" twice to exit.

This should solve the issue.

Please note that this resolution is specific only if you get the exact error message as mentioned in the beginning of this article. There are various reasons you get the "Unable to start debugging on the webserver".

In my case, it was not debugging because -
In Internet Explorer -> Tools -> Internet Options -> Advanced :
(a)Script Debugging (Internet Explorer) was DISABLED
(b) Script Debugging (Others) was DISABLED.

As soon as I enabled these two, it started debugging.

- Amit K Purohit
Also, one has to make sure -
(a) http://localhost is NOT in the restricted site list of IE
(b) Make sure checkbox 1 is selected in IE->Internet Options -> Security->Local Intranet-> Custom Level
(c) You'r a member of "Debugger User" group. (Control Panel -> Computer mgmt -> Local User and Groups -> Groups -> Debugger Groups, add your Id here)

I got this problem after downloading Ie7, because it changes the security setting automatically.

However I found the solution from this site. Thanks very much.

Thanks a 100x!

This worked for me and I am pretty sure I know why after seeing the solution. I have been running ASP.net 1.1 for a couple years no problem (no 2.0 on my machine yet). I just used CCleaner recently and I bet it reset this IE setting back to this default setting.

After installing IE 7 I had this exact same problem. However, I had to change the settings for the Trusted Sites zone instead of Internet (i.e. choose Reset to Low, press Reset, apply). Then restart VS 2005 and debugging now works. :)

IE7 came in with this mornings MS updates and Visual Studio starts thowing up permissions errors everywhere.

This one "CHECK THIS ONE TOO!!! 6/17/2006 3:22 AM AKP" worked for me.

Didn't really want to turn on "Automatic logon with current username and password" for the internet zone.

This thread is going to get plenty of hits whilst IE7 is being distributed. Thanks Bill!!

You can also add the site you are debugging to your "local intranet". I added "http://localhost/" to my local intranet site list and the problem went away

From the security tab just click on local intranet, sites, and add the site you are debugging. I ran into this problem after installing IE 7.

Scratch my last post. My antivirus program had a firewall hidden in it's settings. I got the debugger to start just fine, BUT, when I try to debug my break point's get all messed up. I cleared all break points, then just re-added the one I need by clicking on the line number to make the red dot appear. It doesn't seem to pause on that point. It opens up some other page in my project, EVEN WHEN I REMOVE THAT PAGE! This is why I hate microsoft. Someone plz help ;[

As soon I downloaded IE 7.0 I got this message trying to run my project in Visual Studio.
Solution is already here. Just to make sure gonna put it again.
IE7 -> Tools -> Internet Options-> Security Tab->Click on Local Intranet-> then click button Sites->button Advenced->have typed http://localhost -> button Add. after that steps IE 7 working so far so good.
Thanks for your attention, Eugene.

Thanks Scott. The Local Intranet trusted sites fixed the problem. I tried a dozen things before that without any luck. You would have thought that having http://localhost in the internet trusted sites list would have covered it!
