Accessing websites cross-domain

Hi, we have to international sites with different domains but part of the same forest

Both sites have their own IIS servers and websites

Example: SiteA has DomainA.com and SiteB has DomainB.com

We used to simply use SQL usernames and password for users to get into the website but we are working on AD integration to make it a bit easier

The problem is when a user who is in DomainB tries to access DomainA.com it is VERY slow (permissions seems to work fine as it eventually does come up).....but when the same user in DomainB tries to access DomainB.com it comes up right away

Same thing vice versa

Any idea how to solve this? If the VPN tunnel goes down and a user from SiteA tries to access DomainB.com (and vice versa), what will happen?

Are these different domains under different Forests? Or is it a single forest with 2 domains?

If this is cross-forest trust i would start by checking to ensure that you have the correct firewall ports open. Take a look at the link below which outlines a similar issue you are experiencing.
