I've created a forest trust and have one domain in each (Domain A and Domain B). I cannot add users from Domain B to a domain local security group in Domain A. I can add users from Domain A to a domain local security group in Domain B. I'm not entirely sure what could be causing this issue.
I did notice that when I go to the trust properties in Domain A and select the trust properties I get an error stating: Unable to read forest trust information from the other domain. The error is: There are currently no logon servers available to service the logon request. New naming information is not available.
I'm guessing there is something wrong with the trust on the Domain A side. I'd appreciate any information regarding this.
