If you have forest trust, you should be able adding that users into Domain Admins without any problem.<br />
<br />
Could you describe a little bit more what's happening if you add that user to domain's A group, please?<br />
<br />
Then we will try to solve it :)<br />
<br />
Thank you in advance.<br />
Regards,<br />

<div>
One more question. This is not a Parent -&gt; Child domain relation? Those 2 forests are separate, right?<br />
<br />

<div>
it will never gonna happen without trust relationship unless it is two domains in same forest .. sp lease let us know how it is
</div>


<div>
There are two sepetere forest - so no parent child.<br />
<br />
I have trusts set up in each direction.<br />
<br />
I do to domain admin in domain B - I enter in the username from domain A and I get the sceen asattached below. It will not let me go anyfurther.<br />
<br />
If you click on location you can only see Domain B.<br />
<br />
Are you saying that all I need to do is to add the user to admin in domain A and it will automatically become part od Domain admins in Domain B because of the trust relaionship. Baecuase when i did that I could not logonto the domain controller via Remote Desktop in Domain B, which is what I thought I should be alble to do if it recongiesed me as a domain admin in domian B<br />

Could you simply (stop by step) set out how I can add a user from domain A to have admin rights over all members of domain B.<br />
<br />
I tried adding them to domain admins in admin A but that did not seem to work.<br />
<br />
I know you cannot simply add users from antoehr domain into Domian Admins.<br />
<br />
I have cross forest trusts set uo.
