Causes no end of trouble in $DAYJOB - try to maintina a local file-
share between customers' office PCs and even if Windows isn't being
stubborn about NetBIOS name resolution, it's guaranteed that at some
point the host machine will get a new IP and yet the same damn router
that handed it out will respond to DNS requests with the old IP!

(Set it to a static IP and, guaranteed, some "helpful" local IT mook
will come along a couple months later and switch it back...)

DHCP was a mistake, full stop.
