Unable to read forest trust information from the other domain.  There are currently no logon servers available to service the logon request.

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.

Sounds like name resolution issue. Quoted
Make sure primary DNS and 2nd DNS servers point to each other as primary and themselves as secondary.
If they are in the different subnets, also check the WINS settings.

I have a two way trust established and there is no firewall.  When I try validating the trust on Domain A I also receive the following message:  Windows cannot find a domain controller for the domain.  Verify that a DC is available and then try again.

I noticed in the domain where I'm not experiencing the problem (domain B) that I have a Forwarder configured pointing to domain A's IP address.  In domain A's DNS I do not have a Forwarder pointed to domain B.  Could this be part of my problem?

if you have a two way trust, both sides need to be able to resolve each others dns names, so you really need to create a forwarder on both sides.

From each DC you should be able to succefully ping the other forests DC's by FQDN

I can already ping domain b's DC even though there isn't a forwarder setup in domain A.
