Question

HTTP Error 401. The requested resource requires user authentication.

Asked by: jakobmarkussen

After upgradeing mig sharepoint services server from windows 2003 to 2008 (and IIS 7.0) I no longer can connect to sharepoint site:

HTTP Error 401. The requested resource requires user authentication.

If I disable "Use Integrated Windows Authentication" and IE I can connect to the site. But I have several sites that needs the "Integrated Windows Auth" option enabled. So anyoen know how to solve this after the IIS 7.0 upgrade?

Thanks

Thx. I tried both suggested methods with no luck.

The sites was working fine running IIS6 on 2003 SP2, but not running IIs7 on 2008.

Other ideas?

Thanks.

Looked through the doc. but can't find a solution here.
Something must happen when upgrading to 2008 since it worked before that and if I iinstall a clean 2008 it also works.

I have this in web.config on both working and not working server:
    <authentication mode="Windows" />
    <identity impersonate="true" />
    <authorization>
      <allow users="*" />
    </authorization>

I do not have a <identity impersinare> element in machine.config on either servers.
