Maybe, see below.

It's brand new.

Maybe. This will be a _long_ day at work, waiting to try this at home

Thanks Nathan.

This sounds plausible.  After my linux upgrade I booted up Windows and
never got ADSL to work on it at all.  I didn't associate the two problems
since Linux had just run successfully. Since then I ran `winipcfg' on
Windows and it also showed IP from DHCP server,
same as on Linux.  The weird it that I disconnected the phone line from the
ADSL modem, clicked on `reset', and got the same answer back!  So perhaps
the ADSL modem is storing it somehow.

Leaving everything unplugged all night didn't help this morning (I thought
perhaps something would get reset).
