I am not sure I understand your question.  With Win2k and DHCP, you can
either have the DHCP server register both the forward and reverse
DNS entries, or you can have the Win2k client machine register the
forward address and DHCP reverse pointer.  

If you need to update a zone manually, you can use the nsupdate
utility in BIND.  It has been discussed in the past year, and you can
search the archives.  I have not used nsupdate, as I plan to keep our
Win2k dynamic zones separate from our static zones.  This will require
moving some machines to a new subnet (via router VLANs), so that all
machines on a given 255 subnet 146.137.x.___ will either be all
static registrations or all dynamic registrations.
