Strange dns record registration

Hi!
I have a split-brain dns which worked OK for a very long time. The inner
zone active directory-integrated, the outer zone standard primary hosted by
the computer serving as an internet-access router for my lan with two
network interfaces one looking in my lan, one into the internet, running ISA
Server2000 and RRAS. Until recently this computer had by record in each zone
corresponding to the relevant interfaces. Quite of a sudden the internet
address of this computer started to register in the inner zone, so it has
two host records in the inner zone, one with private address second with
inet one. After I delete the strange record by hand it reappears in a short
while. One of the DCs carrying the integrated zone has a RRAS service on it
serving as a LAN router only, if that matters. All the server computers in
question run under W2000 advanced server with SP4.
What can be the reason and how do I detect the registration of a host record
in the inner zone? I turned on the dns logging options Update and Full
packet but have seen nothing interesting as yet.

Thanks in advance,
Oleg

Go to the NIC->IP client confirguration on the machine for
the EXTERNAL NIC.

Either give it a specific DNS name (e.g., ext.yourdomain.com)
or tell it not to register.

I use cable.mydomain.com and dsl.mydomain.com on my
router.
