DNS Root Hints/Forwarders - Both or one or the other

[SHimmer45]

On a small 2008R2 network (single DNS server on the DC) it has Root hints enabled but it is also set to forward to the council's DNS.

in the "best practice diag" it grumbles that the root hints cannot be resolved and ideally it should be able to do this.

 

the installation is pretty much left as default out of the box so if im forwarding DNS requests should this be disabled? is there a performance gain or is it the best practice menu being overly sensitive?.

DNS should use the forwarders before it tries to use the root hints...

 

Odd that it can't resolve them though!

[SHimmer45]

i havent got any examples to hand perhaps posting them might be an idea

If you don't have a forwarder enabled then it will use root hints to lookup addresses outside of your domain.

 

Can you use nslookup on the server for 198.41.0.4

there is a forwarder enabled, (im not actually on the site where i can test this at the moment)

but do i need both of the options enabled as the local DNS is going to forward requests it cant resolve to the forwarder dns
