debian: dhcpcd with Microsoft Windows2000 server

[Brendan J Simon <brendan.simon@ctam.com.au>]

Our company has a Win2000 Domain server which has DNS and DHCP
services.  I have installed dhcpcd on our Debian Linux machines
(PowerMac G4, PowerBook Pismo and a P133 machine) and they obtain the IP
address and gateway from the Win2000 server without any problems.  The
problem I have is that the DNS *is* being automatically updated for the
Win2000 clients but *not* for the Linux machines.  I can't work out why.

Does the dhcp client on the Win2000 clients work differently to the
Linux dhcpcd ?

Is it a Win2000 server problem ?  Does it use WINS + DNS when using
Win2000 clients and pure DNS when using the Linux dhcpcd client ?  I
know very little about Win2000 and next to nothing about WINS.

Can anyone suggest a solution to get dhcpcd working on the Linux
machines so that the Win2000 server updates its DNS automagically.

Thanks,
Brendan Simon.
