Integrated Windows Authentication + SharePoint + DirectAccess = Internet Explorer cannot display the webpage RRS feed

  • Question

  • Hello,

     

    When I have IE 8 with the "Enable Integrated Windows Authentication" checkbox selected, I get an "Internet Explorer cannot display the webpage" message.  If I disable IWA and re-open the browser, I can access my SharePoint sites without problems.

     

    If I connect via Cisco VPN, I can access the SharePoint site with IWA or without.

     

    It is my understanding the IWA = Kerberos and if IWA is disabled = NTLM

     

    So, does this mean that there is a Kerberos issue?  If so, how can I start troubleshooting for this?  Is it something that the TMG would block by default?  Any pointers?

     

    Thanks.
