ASP.NET Windows Authentication works with IP address in URL, but not dns

I've set up an ASP.NET intranet website with

From another pc: It works perfectly fine if I access it via IP e.g http://11.11.11.1:88/Default.aspx

Unfortunately, when I go to http://MyWebsite.mycompany.com:88/Default.aspx I get a login box popping up.

If I enter username/pass it just rejects it, and I can't get access

From the server: Both IP and DNS alias work. So no problems while on the server itself

Anonymous user access is disabled

Any ideas?

Any suggestions on what further info I can give to help solve this?

Ohh riiight. Got it!

I changed my AuthenticationProvider for my website from "Negotiate, NTLM" to "NTLM, Negotiate"

Following these instructions: http://support.microsoft.com/kb/215383

With a slight change to their instruction to set provider of course

mine:

cscript adsutil.vbs set w3svc/WebSite/root/NTAuthenticationProviders "**NTLM, Negotiate**"

You can get the Website ID by clicking on the "Web Sites" folder on the left in IIS. This should list all your website with their ID

In Internet Explorer options, add MyWebsite.mycompany.com to your list of Trusted Sites.

In Internet Explorer:

  • select "Tools"
  • select "Internet Options"
  • click the "Security" tab
  • click the "Trust Sites" icon
  • click the "Sites" button
  • enter the website domain
    • e.g., http://MyWebsite.mycompany.com:88 (use https if possible)
    • if the website doesn't have SSL, un-check "Require server verification (https:)"
  • click the Add button (don't forget this part)

For Firefox, it's also pretty simple to configure NTLM authentication.

For Chrome NTLM, see this thread.
