dnscmd is for the cache on the server, I expect you would
need to at least be a member of the DnsAdmins group.
Clients have a cache that can be cleared via
"ipconfig /flushdns" on every effected client.
I'm not sure if you must be an Administrator or not, I
would guess so. I think the client's cache has a default
TTL of 1 day for good and 5 minutes for bad.
Yes, each first query for a given hostname gets forwarded
(here is the delay), the answer is returned to the client
and is cached. Any subsiquent queries for that hostname
are then resolved from the cache. As the cache grows,
forwarded DNS traffic reduces.
I just wish I knew the TTL of that cache and the reg key
to set it with.
