in current release only client works under Windows 2000.

When running server, you should get something like:

17:03:58 Notice    Windows 2000 detected (major=5, minor=0), so this 
is proper port.
17:03:58 Critical  | Dibbler - a portable DHCPv6, version 0.4.1

17:03:59 Notice    Parsing .\server.conf config file...
17:03:59 Info      Interface LAN/4 configuration has been loaded.

17:03:59 Info      My duid is 00:01:00:06:44:fe:da:f4:00:0c:29:06:ed:41.
17:03:59 Notice    Creating multicast (ff02::1:2) socket on LAN/4 
(LAN/4) interface.
17:03:59 Error     Unable to join multicast group.
17:03:59 Critical  Proper socket creation failed.
17:03:59 Critical  Fatal error during TransMgr initialization.

It fails, but it should definitely get further than to "Parsing 
.\server.conf config file...".

I finally managed to find what is wrong with "Unable to join 
multicast group" and fixed version can be downloaded from:


Give it a try, it works for me here.
