DNS best practices?

-

are there quides ms server dns services easy follow?

i tried reading files, ms step-by-step guides, , either dumb or pretty hard follow , understand, or dns configuration cryptic in itself.  or of above. :)

seemingly, there aren't many scenarios small businesses single server: dhcp router, dhcp server, static addresses.

most common scenario dhcp @ server, assume - , in case, should dns like?  should ip configuration on clients , on server like?  this:

clients:
- dhcp-issued address
- gateway, dns: server ip address

server:
- static ip address
- dns servers:
  - its own ip address?
  - router's or isp dns addresses

it shouldn't hard settings should in simplest of configurations, , yet having hard time finding info!


scenario 2: dhcp @ router, server getting static (reserved) ip address, e.g. 10.0.0.5.

router: 10.0.0.1
wan dns/gateway: pre-configured or dhcp isp
lan configuration: dhcp clients with:
 - gateway - 10.0.0.1
 - dns 1: 10.0.0.5
 - dns 2: 10.0.0.1

server ip: 10.0.0.5
 - gateway - 10.0.0.1
 - dns 1: 10.0.0.5
 - dns 2: 10.0.0.1

does sound right?

if so, should dns configuration in scenario?

thanks clues!

alex,

yes - correct (to specific, able out internet, not resolve dns names - minor exception of records present in the client's dns resolver cache)...

a "clean" way handle set server in site functioning dns server (and, if possible, ad dc) - giving level of redundancy - sounds not option have available...

in general, not recommended point ad clients external dns servers. mitigated setting isp dns secondary, but you need evaluate whether potential local name registration/resolution issues justify ability use internet during server outage. however, not apply dns client settings on dns server - should point (note in case, same reasoning not apply, since assumption server down).

one possible (although bit cumbersome) alternative would take advantage of alternate configuration. more specifically, could configure domain members dhcp clients dhcp server running on dc, , set static settings under alternative configuration each, pointing external dns server. in addition need add users local network configuration operators group. if server fails (assuming hardware/os level failure), users need perform dhcp release/renew...
