On a new installation of IIS 7.5 I have setup Windows Authentication on my Intranet.

The providers I have used are 'NTLM' and negotiate in that order.

This works fine in IE and Firefox but in chrome I get the following

This web page is not available The web page at http://mysite.com/myintranet.php might be temporarily down or it may have moved permanently to a new web address. Error 338 (net::ERR_INVALID_AUTH_CREDENTIALS): Unknown error.

I've tried looking online for a solution without any success.

I'm running the latest version of Chrome 21.0.1180.60

This is a very well known and old issue. However, Shawn Weisfeld provided a year ago a solution on his blog:

The fix was to force the web server to use NTLM. To do this in IIS 7 is just a setting in system.web/system.webServer/security/authentication/windowsAuthentication/providers section of the web.config
