RE: DNS cache poisoning?

This appears to be related to a well known issue.

Windows DNS is subject to cache poisoning if forwarding to BIND 4 and 8
servers, which do not properly scrub data. Forwarding to BIND 9 should work
OK because BIND 9 works properly. 

So "dump Windows DNS and use BIND" does not adequately cover the issue.
