DNS cache corruption

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I have a horribly confusing problem. Have a client who three times in the
last week has had every entry in their DNS cache on a windows 2000 server
set to the same IP address. The address, all three times, resolves to
www.jothan.com. Every website not resolved directly by the internal DNS
server redirects to jothan.com. The reason I worry about this is that this
is a site run by Jothan Frakes who is a DNS TLD expert influential with
ICANN. If I simply clear the DNS cache, it is not fixed and the cache sets
every entry back to the ip of www.jothan.com. If I restart the DNS server,
then clear the cache it is fine for a day or so.

The second worry I have is that this issue started first thing the morning
of April fools day.

Anyone with any idea whatsoever? They are using root hints and we switched
to forwarders, just in case.
