Username and password over 2 domains

[Bad boy Warrior]

I have an intranet site which is used over two domains (with a trust). The problem i have is if a user on Domain B navigates to this site, they are requested to enter their full username and password i.e. domainb\user where any users on Domain A dont have this issue (as the intranet is hosted on this domain).

How could i overcome this issue so users on Domain B do not have to enter any credentials and is automatically logged on? (Note: to authenticate a user i have AD setup with SQL)

Thanks

Do you have a 2-way trust in place? You need a trust in each direction. A typical one-way trust between domains is: A (user accounts) [trusting domain] -> B (resources) [trusted domain]. Users from A are allowed to access resources on B. Set up another trust between domains in reverse of the initial and then you will have your 2-way trust.

I am going to assume some things here so bear with me if they are incorrect

The intranet is hosted in Domain A

You log in onto domain A and no login prompt

Log into Domain B and the login box appears.

If this follows your problem then all you have to do in Domain B via GPO, Local IE settings is add the Intranet as a Local Intranet site

If this does not solve the problems then post screenshots
