	A refresh query is equivalent to "dig soa <zone> @<server> +norec".

	You should get only the SOA record for the zone in the
	answer section and "aa" should be set in the flags field.
	If you don't then there is a error on the master.

	Mark

e.g.

; <<>> DiG 9.3.4-P1 <<>> soa +norec dv.isc.org @::1
; (1 server found)
