What happens if I change my clients to point to my 'Router/Gateway'
for any/all DNS calls, AND, SELECT "DNS Relay" on my router?
Clients will query the router, and the router will query your configured
DNS servers if it needs to. Unless configured otherwise, clients won't
go directly to your ISP's DNS servers.
The advantage of this is that if the router already has the answer then
it can just give it - it caches results for all clients that use it. The
disadvantage is that the router may actually slow down DNS queries by a
tiny amount - it's more work to process the queries and check its
internal cache (if the entry is not cached) instead of letting the
client go directly to your ISP's server. The difference is so small that
I doubt there's any way you would ever notice. It also lets you easily
switch DNS servers for all your clients if they use the router - only
one place to change instead of visiting each client.
It's most useful when clients get their configuration through DHCP.
It seems that I push more work upstairs where services exist, rather
than churning around within my LAN where answers do not exist. And
no, I do NOT use a Domain Server, yet!
Thank you,

This has nothing to do with Windows domains - DNS has existed and been
working for longer then Windows has been on networks.
