veryify that an ad dc is available and try again." That happens when I try and validate one side of a forest trust.
Here's my scenario: I'm trying to setup a two way, transitive forest trust between forest a and forest b. The validation process is successful from forest A side. When I try and validate the forest trust from B side - I get the error I listed. Additionally, when I run nltest /dsgetdc:example.com (forest b)I get the following error: getting dc name failed: status = 1355 0x54b error_no_such_domain.
However, the same command completes successfully from forest A side.
I created secondary zones in each forest and I can ping the fqdn names successfully. The only difference I can find is the domain zone for forest B has the _msdcs directly under the zone. In contrast, for forest A, i had to create a secondary zone for the _msdcs and transfer it forest B becase this zone was not included as it normally is under the domain zone label. I think this is causing the DC is Forest B to be unable to locate the SRV record for the forest A DCs even then the DC has a secondary zone which includes these records.
Anyway, your help and recommendations are greatly apprecaited.
