	The length of the chain of nameservers required to resolve
	this particular name is to long for BIND 4 to succeed.
	BIND 4 and BIND 8.2.x assume that nameservers are setup in
	a sane manner, i.e. they serve the zone they live in.

	Upgrade to BIND 9 which can handle this configuration.

	Mark

passau.de.              1D IN NS        ns.nameserver121.com.
passau.de.              1D IN NS        ns2.nameserver121.com.
