Ok, you *have* confused me with the OP. We run almost *no* Windows here,
at least on the servers or workstations we support in this division. They
do actual science here, and Windows...rotfl! running scientific compute
clusters? To do what, figure out the first 100 decimal places of pi in a
month?

And running another DHCP server on the network is *not* a Good Thing, and
I feel as though we'd get a lot of grief if we did. Rules and regulations,
forget "corporate" rules.
