Question : Cross-forest trust:  The domain controllers required to find the selected objects in the following domains are not available

I have the following domain configuration in place:

Corporate.com <- one-way trust <- qadev.local <-> dev.qadev.local

I am able to add [email protected] as a local administrator to machines on qadev.local, but not to machines on its child, dev.qadev.local.

When I attempt to add to the local administrators group on any machine to dev.qadev.local, I can browse corporate.com and select the user, but after this that I receive the error:


The Active Directory Domain Controllers required to find the selected objects in the following domains are not available:

corporate.com

Ensure the Active Directory Domain Controllers are available, and try to select the objects again.

Am I missing anything in this design. Should children of the root be able to piggy-back on the root's trust, or do they require their own trusts to corporate.com for this to work?

Answer : Cross-forest trust:  The domain controllers required to find the selected objects in the following domains are not available

It appears the trust between child and parent was broken.

I reset the trust username/password and am now able to add users from corporate.com to dev.qadev.local.

Thanks for the assistance.
