[lug] DDNS update-style

I have an internal resolving/caching DNS pretending to be authoritative to
our domain from those on the LAN.  Using DHCP I am updating this NS
dynamically with the 'ddns-update-style interim;' in dhcpd.conf.

In the past I have had trouble with the NS not resolving after a period
of time.  It would only resolve inside addys and nothing on the
Internet.  So I started from scratch.  Previously I was using ad-hoc and
that seemed to work great except for NS quiting outside res.  I changed
to interim because The Official Red Hat Linux Customization Guide says
ad-hoc has been deprecated and recommended to use interim.

Problem with interim is that it seems to only register pre-win2k.  I see
the w2k boxes getting their address and renewing fine, but it's not
writing to the DNS.

On another note, the NS is still stopping once a week or so resolving
outside addresses.  Much better still since it's not within the previous
10 minute stint.  I test this by doing a nslookup <host> and find who
gives me the answer; my NS or the secondary ISP's NS.  Restarting named
and retesting after a few seconds always works.

My problems? Internet problems? Both? Need sample configs?
