So it's an indication of W2K's brain-deadedness then, that it stores a
SERVER setting as "option 51" which option 51 is really a
client-setting? I've chatted with the network engineer who maintains
the W2K dhcp server here and he's confident that the figure stored as
'option 51' is in fact the server-supplied lease time, an analog of the
default-lease-time. Bizzare, but easy enough to work around for me.

Right, MCLT / etc, correct? But for the purposes of the dhcp.conf file,
no extra complexity, right?
