Unable to start debugging on the web server. Debugging failed

"Unable to start debugging on the web server. Debugging failed because
integrated Windows authentication is not enabled.

Please see Help for assistance" - What could be the problem?

in case the project is on local IIS server, you need to enable Integrated
Windows Authentication on the local IIS.

1. Open IIS Manager (Internbet Information Services)
2. Right-click the web site (in case you run it locally you only have
Default web site) and pick Properties
3. Choose "Directory Security" tab and click Edit on "Anonymous access and
authentication control"
4. In the opening window, uncheck "Allow Anonymous access" and check
"Integrated Windows Authentication" (allowing anonymous can make that you
don't have enough permissions to debug)
