I have just created a small SharePoint Foundation 2010 farm. * Active directory (domain = MyDomain.local) * SQL Server (member of MyDomain.local) * Web front end (member of MyDomain.local)

Everything works fine when on LAN, but when trying to acces through internet with public domain name (, there is no response : I am correctly prompted to set my credentials, the farm seems to work, but the welcome page is never displayed.

Do you have any idea of what is occurring ?

In the logs, some times, I have an error mentionning that I a m not allowed to access an iis config file, and sometimes, I do not have any error.

Please heeeeeelp :)

thank you everyone for any help and sorry for my ugly poor written english

regards, Laurent MONDEIL

  • Actually,
    my WebApplication's default zone'url is and I have no other zones declared
    the IIS site host header is on port 80

  • When you say "Check that you end up on the correct IIS web site", what do you mean ? How do I check this ?

  • Firewall is configured to allow trafic on ports 80 and 443 for World Wied Web Services

  • Check your Alternative access mapping (under Application Management). You need to set one up for your public address. you might need to configure Host headers in the IIS too.
  • Check that you end up on the correct IIS web site.
  • Also verify that you have your port 80/443 in the firewall.

First of all, thank you for helping me. – user8683 Aug 8 '12 at 6:44
In IIS add a index.html page to the root folder of the IIS Default Site on port 80 (Not the SharePoint created web site on port 80), add some content in it just so that you know that it's that file you will receive. And then try to access you site from the public URL. If you get the response of the HTML file you just created you know that your are at the wrong web site and can configure IISfrom that. – Robban1980 Aug 8 '12 at 7:43
