I have Asp.net website for domain A users with the Integrated Windows Authentication.

Now users from domain B need to access the website.

But Domain B users receive pop-up window to input the authenticated information when they access the website

My question is:

How to configure the IIS or Windows Server to allow Domain B users to access the website without the pop-up windows for authentication, just like the users from Domain A.

    Are they in the same forest or have a trust between them? – Gary Jun 05 '12 at 03:30
  • Gary,thank you for your reply. Domain B users can open the website as long as they input the username and password of Domain A. I'm not sure whether they are in the same forest or have a trust. How can I know? – macemers Jun 05 '12 at 03:36
  • Gary, not if he's writing the code in C# or VB.NET. What code are you using to authenticate right now? Are you strictly relying on IIS to do the authentication? – jcolebrand Jun 05 '12 at 03:38
  • To jcolebrand, yes, I set Integrated Windows Authentication in the IIS. – macemers Jun 05 '12 at 03:48
  • jcolebrand, my thoughts were this is a server configuration issue; I digress. – Gary Jun 05 '12 at 04:34
  • Somebody helps. It's quite urgent – macemers Jun 05 '12 at 05:08

  1. Check that you have a trust configured

Verify this by trying to add domains users from domain B to the file system where your IIS site is located.

  1. Verify that the correct user group from domain B has access to file system where your IIS site is located. ( if not using domain users from domain B ).

  2. Verify that the user that is testing from domain B has the correct group memberships.

And if running Kerberos authentication.

Check on client where the user is if you have a kerberos ticket by using command "klist tickets"
