reverse lookup

[james]

My AD DNS servers are configured to forward queries outside the AD zone to
another server (Unix box running BIND 9). I have no problem doing forward
lookups to that server from the AD zone. But the reverse lookup does not
work. For instance, on the Unix DNS box, I have the following entry:

server1.corp.com IN A 10.10.10.1

If I say, ping server1 from the AD zone, I get a full response. However, If
I do ping -a 10.10.10.1, I get reply from 10.10.10.1 but no host name
although a Reverse lookup zone is already defined on the Unix box. If I do
the same on a machine which is not member of AD, I get full reverse lookup
response. Any reason? Thanks

Does your AD DNS server have a copy of this reverse zone on it?

No, it does not have a copy of the Unix DNS server Reverse Lookup zone.
There's a Reverse Lookup zone defined within AD which is dynamic & covers
only systems which are part of the AD Domain.

Make a copy of it and your probs should go away.
