Today I installed some new products from the overlays on an SP4 server.
Perhaps it was because the ISO I was using was SP4_a_ but it seemed to
want to install the DHCP server again, and I let it.

After I rebooted the server, it had commented out my DHCPSRVR line and
it took me a while to track down why one of my users couldn't get an IP

Since I have multiple servers in my tree but nothing clustered, is there
a way for NDS to somehow figure out that a DHCP server ought to be
running somewhere and start one up if there isn't?
