clearer picture of network.
10.5.1.x contains a win2k DC with DNS(AD integrated) and DHCP passes
ips to .1.x
10.5.10.x now contains a demoted win2k box (member svr) with DHCP
passes to .10.x
10.5.20.x contains a win2k3 DC with DHCP ips to .20.x
10.5.30.x contains a win2k mbr svr with DHCP ips to .30.x
10.5.40.x contains a win2k3 DC with DHCP ips to .40.x
10.5.50.x contains a win2k mbr svr with dhcp to .50.x
I am getting the errors from the .10.x server on the .1.x server
running dns. but DNS is not even being updated correctly for a pc
brought into .1.x
subnet (where the dns server is). I have added (overkill) all the dhcp
servers to the dnsupdateproxy group to no apparent effect.

This would still require a change of ownership of registered records. The
DnsUpdateProxy group is not secure and the DHCP server will have to take
ownership of the records. The problem is if a machine registered its own
record the DHCP server can't update it and vice-versa. Once the DHCP server
takes ownership, the client cannot update it.
Check the Advanced security of the records to see who the current owner is
and what the Effective permissions are for the DnsUpdateProxy group.
