IIS / Web Development

• Unable to start debugging on the web server. Debugging failed because integrated Windows authentication is not enabled. Please see Help for assistance :

• Make sure that IIS is configured to use Integrated Windows Authentication. Look for the checkbox on the Authentication Method dialog launched from the Directory Security tab of the site properties.

• Make sure that HTTP Keep Alives are enabled. You'll find that checkbox on the Web Site tab of the properties dialog, in the connections section.

• This one is strange, but it seemed to do the trick for many out there, add http://localhost to the trusted sites in Internet Explorer. To tell the truth, this seems to be a fix for the symtoms, not actually fixing the problem itself, but if it works it works. BTW, you'll have to uncheck the “Require server verification (https:) for all sites in this zone“ checkbox to add it as a trusted site.
