	Well there are DHCP options for setting the search list.  I would
	hope that with 2500 PC's that you were using DHCP.

	The reason that 4.8.1 worked is that any query that was a single
	label (excluding the root label) could have a domain appended to
	it by the server before it was looked up.  See the domain directive
	in named.boot.
