If people set up their Win2K networks right, it wouldn't be a problem.
Simply install the MS DNS server, point their clients at that, then all the
updates go there. And if that DNS server has connectivity to the 'Net at
large, it will resolve all their other requests too by chasing the chain
from the root down.
Best of both worlds, or at least the best you can do in the situation ...
