Does anyone have any experience with NT4's DNS server? Does it work
well with a split DNS environment? With multiple subdomains &
primaries & all the other curves that can make split DNS a challenge?
While I have no direct experience with NT's DNS server, I seem to remember
mention on this list of it working well with other NT DNS servers, but not
working properly with Unix-based servers, when one is a secondary of the other.
The person reporting the problem at the time said that MS ackowledged that the
incompatibility existed, but claimed that they had implemented the spec, and
everyone else was wrong. You may want to check on this, before counting on
using it for split-DNS, unless you have all NT machines in the setup.
Also, check out the security advisories on NT's DNS server. It can be crashed
(for a nice DOS attack) simply by sending a reply to a request which was never
made.... It *may* also be vulnerable to the "port 135" attack. (Most of MS's
networking code is vulnerable to random garbage sent to its ports -- causes a
runaway process which eats all idle time.)
