Hey,
i have weird issue in my environment, when i configure the DNS of the customer i getting error of "WARNING: DNS unreachable"
i check that all the A record and the PTR that configure on the DNS side and its look ok.
after i not found any problem i run diagnose test on the server and i see that i see validate_network problem "Reverse DNS lookup mismatch" , i check again the PTR and its seems ok to me.
i run another test of all the nodes in the dns:

its look ok to me i cant see any problem here.
i see that there is bug in cisco "CSCvo01169" that talk about that, i asked from the customer to check about that, but in still want to be sure that it not another problem.
anyone see isuuse like that?
