Hello   As part of a systems migration to RA Airways I am required to to remove RA subdomains from our DNS (that we were formerly authoritative for) and forward them to our Untrusted DNS which then on -forwards to the RA net DNS servers for the correct (un NAT'd) resolution.   I am doing a trial domain at first.   I removed the secondary and primary servers from the domain of "tpf.uk.ra.com" Then I updated the secondary DNS servers then the primary server and the old (NAT) addresses ceased being resolved. I then put the following DNS forwarder statement in the 'options' of the DNS server   zone "tpf.uk.ra.com" {     type forward;     forwarders { 10.142.20.60; 10.142.20.61; 10.141.20.60; }; };   Then once again updated the DNS server When I try to resolve the host (which will now depend upon the forwarder statement in named.conf file) it does NOT resolve&.. ============================================================ dho51@starasv109> nslookup bsslive.tpf.uk.ra.com Server:         127.0.0.1 Address:        127.0.0.1#53   ** server can't find bsslive.tpf.uk.ra.com: NXDOMAIN   dho51@starasv109> =============================================================   However, when I force the lookup to the the first address in the forwarder statement, it does work Any idea what might be wrong. (See below for forced lookup with the desired resolution)   ================================================================== dho51@starasv109> nslookup bsslive.tpf.uk.ra.com 10.142.20.60 Server:         10.142.20.60 Address:        10.142.20.60#53   Non-authoritative answer: Name:   bsslive.tpf.uk.ra.com Address: 62.208.174.139 Name:   bsslive.tpf.uk.ra.com Address: 62.208.174.12   ===============================================================   Any ideas what might be wrong with what I am doing???
