Integrated Authentication IIS 6.0: 401.1 with IE7

Question

Today I changed the application pool identifier of our ASP.NET application from Network Service to a domain user.

I added the user to the local group "IIS_WPG" by running iisreset just in case, and everything works fine with IE6 and Firefox 3.0

But when I go to the site with IE7, an authentication popup appears, I type in my credentials, and then:

HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials. Internet Information Services (IIS)

Any ideas?

Answer 1

Typically, if you see an authentication problem where it works in IE 6 but not in IE 7, I would check to make sure Kerberos is configured correctly.

Kerberos :

cscript adsutil.vbs set w3svc/###/NTAuthenticationProviders "NTLM"
