I am currently trying to fix an issue with my companies AD structure.
I have had this issue but I cannot find my answer on the internet yet
so I will post here with hope that the community can help me out.

Currently I have AD structure similar to the drawing below.

<rootdomain.int>
|
|
<domain.int>

rootdomain.int has only a few DC's and 4 real users, just a empty root
domain
domain.int is where all the servers, groups, users and etc are.

When on a member server from the "domain.int" domain I cannot access
the rootdomain.int domain. I get access denied no matter what I do. I
know the user accounts I am using (from both domains) have access as I
can login to the DC's at the rootdomain.int with them. Plus they are
Domain Administrators or something comparable.

Anyone have any ideas? I seem to remember something about
authentication and a GPO but I cannot put my finger on it yet.

Peter

Is domain.int a child domain? If so, it should be in the form of
domain.rootdomain.int.

If not a child, is it another tree in the forest?

If a true parent-child, this issue maybe a DNS resolution issue. How is DNS
setup? Is it a delegation? Can you post an unedited "ipconfig /all" from a
DC in rootdomain.int and from domain.int please? This is important to help
us to understand your infrastructure, name resolution, and DNS setup to
better assist you.

Hello PeterCS,

Does rootdomain.int and domain.int are different forests? Or is domain.int
originally domain.rootdomain.int? Did you create a trust between them? How
is DNS setup?

Best regards

No they are in the same forest as a child / parent. As a side note I
did figure it out. It looks like it was a group policy applying to the
server / OU. After I changed OU's I had no more issues.

Ok, great! Glad you figured it out!
