	It does however *transmit* and *cache* them.  If you want
	to *publish* new RRs then you need to upgrade your dns
	server to ones capable of publishing them.

	Note it is possible to upgrade the DNS servers and *still*
	have active directory support.

	No they wouldn't.  They would replace the offending component
	with one that does the job required.

	A compentent system administator would use all the tools available
	to them.

	I never said it was.  There are multiple nameservers that
	run under Windows that are capable of do the job.  There are even
	more that run under other OS's that can be intergrated into the
	solution.

	The fact that you seem to want to restrict the solution space
	to only Microsoft Windows servers on a Windows box is what has
	clouded your judgement.
