[SOLVED?] write_socket_data bug

The process of setting up reverse DNS depends on
a) What operating system you are using
b) The DNS server you are using.
c) What range of IP addresses you want to do reverse lookups for.
Assuming a unixy type OS, Bind 8 and 192.168.0/24 then you need to edit the
/etc/named.conf file and add something along the lines of
zone "0.168.192.in-addr.arpa"{
type master;
file "rev.192.168.0";
};
The file rev.192.168.0 would then contain
@ IN SOA your.name.server. root.your.name.server. (
2000102700 ; serial
10800 ; refresh
3600 ; retry
604800 ; expire
86400 ; default_ttl
)
; default ttl when ttl not specified
@ IN NS your.name.server.
@ IN NS your.delegating.nameserver.
@ IN NS your.secondary.server.
1 IN PTR the.machine.192.168.0.1.
etc, etc....
Under linux, linuxconf simplifies this process.

This sounds like exactly the solution to the problems I've been having -
could someone describe the process of adding reverse DNS in simple terms for
novices like me?
Many thanks - the list has been quite helpful and I appreciate the gathered
wisdom of all you subscribers.

I can confirm that adding reverse address lookup seems to solve the problem.
Since we added reverse DNS about a week ago, there has not been a single
write_socket_data error message in the samba logs. Many thanks for this
useful tip.
