sorry about the late reply to this, this was something I was doing in my part time. I feel kind of stupid, but hope my mistakes will help others, I have learnt:

If you are managing dns be VERY pedantic about syntax in your zonefiles, make sure you stick closely to what is reagarded as a template zone file - after messing about with backups I had made of the zones which did not work I realised that it was my syntax which was wrong at one or two places, and this was enough for any queries to not work on those zones. My advice is to get the DNS and BIND book from O'Reilly, this helped alot, and also create a .template file in your /named directory (which just has a template for the SOA down to TTL header of zone files) and whenever making new zones, use that to copy from, it is very useful. Finally after making so many changes and losing my trail I decided to put my whole dns zone file editing under SCCS control, this way I can keep an audit trail of what is done, when and why - I have found it very useful indeed. SCCS is good, and simple, for that. man SCCS for info.

Hope this prevents someone having the same grief I had!

NAME
named-xfer - Pulls BIND zones from another server SYNOPSIS
/usr/sbin/named-xfer -z zone_to_transfer -f db_file -s serial_no [-d debug_level] [-l debug_log_file] [-t trace_file] [-p port] [-S] servers... OPTIONS
Specifies the name of the BIND zone for the named-xfer daemon to transfer, for example, dec.com. This option is required to pull a zone. Specifies the name of the file into which the pulled zone information is placed. This option is required to pull a zone. Specifies the current serial number of the SOA record for the zone zone_to_transfer. If serial_no is set to 0, the zone is always pulled. This option is required to pull a zone. Sets the debug level and determines the amount of debug information to be displayed. Specifies the file that will contain any debug messages from the zone pull. Specifies the file that will contain a trace from the zone pull. Specifies the port that will be used instead of the default name server port listed in /etc/services. Performs a restricted transfer of only the SOA, NS records and glue A records for the zone. The SOA record is not loaded by named, but is used to determine when to verify the NS records. See named(8) for more information. Specifies a list of Internet addresses, in dotted-quad format, from which to pull a zone. If the first host cannot be reached, the named transfer daemon tries to pull the zone from the next host listed. DESCRIPTION
The named transfer daemon, /usr/sbin/named-xfer, is a server that is usually run by the named daemon, /usr/sbin/named, but it can also be run manually with the given arguments. The named transfer daemon runs on a BIND secondary server and pulls BIND zones from a primary server. This daemon is not run by default, nor can it be started up from inetd(8). SEE ALSO
Commands: named(8) Files: resolver(4), services(4) named-xfer(8)
