There is a bug in the current developer version causing all recent
versions not to be able to run on NT4. The problem lies in the interface
detection routines.  See https://ntp.isc.org/bugs/show_bug.cgi?id=450

This seems to be a bug in the installer, but I was able to install the
service here under NT4. Did you try to install it using the SYSTEM
account (in order to be sure that this is no access restrictions related)?

No, they should contain different exe versions, but I'll check that when
I get back to my desk on Monday.

No, that version contains a workaround for bug #450, it overrides the
interface detection routines and simply binds to the first interface it
sees. This version is only usable on systems with only one interface
(i.e. one network interface card and one TCP/IP interface). I created it
for a few customers who experienced the same problems (no remote  servers).

Kind regards,
