We have an intranet application running on healthcare.yourdomain.co.uk.
We have deployed this application in a server belonging to mydomain.com domain. We have configured this application to use integrated windows authentication.
We have configured this application in server100.mydomain.com. (NetBIOS name DOMAIN).
Windows 2003 SP2 & IIS6.
We have created one more DNS entry healthcare.yourdomain.co.uk pointing to server100.mydomain.com.
We have configured the website for healthcare.yourdomain.co.uk on server100.mydomain.com
And I have placed a header healthcare.yourdomain.co.uk.
Our users PCs are in mydomain.com. (NetBIOS name DOMAIN).Whenever user types healthcare.yourdomain.co.uk in IE they are prompted for login window, it never consider integrated windows authentication. When I enter DOMAIN\myuserid and password it comes up with the website.
But when we try to access the application using server100.mydomain.com (we have configured this application default website and configured server100.mydomain.com & healthcare.yourdomain.co.uk as host headers), no auth prompt is shown; users are directly logged into the application
Ideally, when we try to access healthcare.yourdomain.co.uk the authentication prompt should not have come and users should be seamlessly logged into the application. What is the resolution of this problem?
Our users in mydomain.com. (NetBIOS name DOMAIN) should be able to access healthcare.yourdomain.co.uk without any prompt (it should use integrated windows authentication).
