Reverse DNS, PLEASE HELP.

[sanam]

I have a client whose registrar wont let his customers domain to pint to his nameserver.

It gives out this error:

Contacting and examining info at &ns.domain.com& (IP.IP.IP.IP)
ERROR: ***Reverse*** DNS not setup and running for IP.IP.IP.IP
! You may have an SOA record - but I can't get to it with 'nslookup'

It gives this error for both nameservers.

Please tell me what i have to do ?

Thank You

Did you add an A record to named.conf?
