While zone domain-named data is properly transferred from the zone master server to a zone slave server, the reverse domain data is not being transferred. In other words, the host.rev file on the slave is not being properly updated from the primary.
Possible causes
Syntax error in the slave server's boot file.
Diagnosis and Solution
Check the slave server's boot file. Make sure that the master server's IP address is listed for the reverse zone entries just as it is for the hosts data.
