SBS 2000 - Event ID 4000s every five minutes

I'm running SBS 2000 on a single-homed machine with DNS listening on the only
I.P. and pointing to this I.P. as preferred DNS. Indeed, the server has been
running without issue for over a year and no changes have been made
recently...

The problem now: Numerous event id 4000 are generated in DNS log (every
five minutes). The server eventually becomes unresponsive - cannot login,
access Exchange, files. Reboot rectifies the problem, then after an approx 3
day interval the events appear again and reboot is required. This cycle
continues...

I've run dcdiag/netdiag and no failures are indicated. DNS seems to have
all appropriate srv records etc.

Any input would be greatly appreciated - I've done a fair bit of research
but none of the articles that come up apply to my issue.

Many thanks in advance.

Preferred? Should be the *only* one....all clients and servers must specify
only that IP for DNS. Forwarders on the SBS/DNS server should take care of
answering queries for external names.

Might want to post in m.p.backoffice.smallbiz2000 for more help, as SBS does
a lot of things its own way (including patches; you haven't mentioned what
SP/etc you're on). Also look up your errors at www.eventid.net .
