I just have a general question as to what is the best practice for configuring DNS on a server. Both in the LAN connection and the DNS server role. All my servers are a domain controller with DNS server role configured. There is no exchange running on the servers and all my clients are very basic small business network setups. The servers are basically just being used to share files and authenticate users (AD). Because I took over the majority of these customers from a different IT tech the DNS is setup differently on some of them.
For example if the LAN settings are as follows:
IP - 192.168.1.100
Sub - 255.255.255.0
GW - 192.168.1.1
How would I then configure the DNS???
Some are set to 127.0.0.1 as primary with nothing as the secondary.
Some have the IP as the primary with the ISP as the secondary.
Some have one number higher than the IP (192.168.1.101) as the primary and the IP as the secondary.
I would like to set all my networks the same and would like to know the best way to do it.
As far as the DNS server role all the servers are set to listen on all IP's and some have forwarders and some do not. The ones that do not have forwarders are the ones where the DNS is set to 127.0.0.1 for the primary LAN and the ones that do have forwarders are set to the ISP DNS. Again I would like to know what would be the best practice for setting DNS forwarders.
Thanks for your help!
