rt-ac86u dhcp and windows server 2012 r2 dns

[ludo14]

Hello,

RT-AC86U Router setup as DHCP server
Windows server 2012 R2 as DC and DNS server

In router lan > dhcp server what should I put in the rt-ac86u domain name?
domain.local
or
ac86u.domain.local ?

In router lan > dhcp server is there an ability to type two dns servers?
Or would typing only windows dns server ip then router will give out itself dns as secondary?

Would the router be able to update windows dns server dynamically if leaving security as unsecured and secured?

Right now when looking at network neighborhood the only computers listed are the few important ones I have manually typed in the windows dns.

The reason I was thinking to do it this way is in case DC is having a problem the rest of the network will run.
There is a second server for file sharing.

Don't use a domain ending with ".local" as that's a reserved name. Use something like "mydomain.lan". That way your clients will be called something like "server1.mydomain.lan", "printer.mydomain.lan", etc.

I don't believe so, it will be down to the client to register its name in DNS. That's the advantage of having the domain controller running both the DHCP server and the DNS server, DHCP can update DNS. The same thing would happen if the router was handling both DHCP and DNS (dnsmasq does that).
