Conditional Forwarder Not Fully Working

-

our comapny aquired another. set trust , conditional forwarding each other.

my side working fine. when they do ns lookup side not returning domain controllers in results. cannot browse domain via aduc.  odd thing can ping domain controllers fqdn.

if replace conditional forwarders secondary zone, nslookup returns dcs , can browse directory.

could firewall blocking kind of query or response from the forwarder?  can telent on port 53.

an asa firewall was dropping dns packets on response. the acquiring company has extended dns probes enabled default in windows server 2008 r2.

we had disabled ednsprobes on our side when had cisco pix firewall not handle larger packet sizes. on asa's can adjust allowance packet size going do. there apparent benefits using extended dns.
