Does DNS cache forwarder lookups?

I have a Win2K server w/ AD, DNS, DHCP. DNS is set up with forwarders to the
ISP's DNS servers in addition to acting as a local DNS. Does the Win2K
server DNS cache resolved replies it receives from forwarders? If so, where
is the cache located?

In the DNS management cosole, select View> Advanced. You will see the server
cache.

Yes.

Unless DNS caching is disabled, it caches anything it has to
look up (recursion or forwarding responses.)
If so, where is the cache located?

The trick is to turn on "Advanced view" and then the cache
display is right there in the left hand browsing tree under the
server with the Forward and Reverse zones.

I almost never look in there by the way -- there is almost never
a reason.

Damn! If it had teeth I would have been a dead man. Thanx.

(Miracles are simple to perform. It's the obvious stuff that seems to take
forever!)

Thanx. Far too obvious for me to have found on my own.
