I have DNS installed by default when i installed AD. I also have my DNS server setup to use a forwarder on the internet. My internal dns is 192.168.0.225 the forwarders are 12.106.72.14 and 12.106.72.12 All seems to be working fine, but i want to know what Ip's should i put in place on my internal dns server to use for dns,and what IP's should i use on my isa server for DNS. If I use a forwarder should i just point everything to my internal DNS, and let the internal DNS use the forwarders? for example. internal dns would use for prefered 172.0.0.1 alternate 12.106.72.12 ISA would use for internal nic prefered 192.168.0.225 alternate 12.106.72.12 External nic preferd blank alternate blank. is this correct? THanks for any advise
