On Windows 2K? This is a host trying to insert a dynamic PTR record into your DNS. That is usually a function of a DHCP server, and can be configured if desired. If you haven't configured dynamic DNS, then it's harmless apart from taking up space in your log files. W2K is notable for shipping with the dynamic DNS stuff turned on. It's not just you: seems a lot of W2K machines try to update records in the root servers too... Search for 'Syslog Errors' in http://www.caida.org/outreach/presentations/ietf0112/dns.damage.html for the depressing statistics.
