I am looking for the proper config of active directory and dns in my local w2k domain. I currently have 2 DC'c in a domain and the primary running dns alone. I am worried about it failing and trying to implement redundancy amongst them. I want to add a second dns to act as a secondary/ backup and assume it should be setup on my second DC. My questions are as follows. But confused on the diffensce between a secondary dns and a backup or are they the same.
Q1 If the primary DC goes down I want a secondary dns to kick in. how do I do this?
Q2 In DHCP, should I give it both IP addresses of the above 2 DNS server so if the primary fails, the secondary kicks in. Right now when i shutdown my Priimary DC, I instantly get a notice in my workstation event viewer " can not locate dns".Does the secondary dns mean it will point to my backup dns in case of faulure? or is this done automatically without adding that second dns address on my workstations IP config
Q3 In my second DC , dns was turned off and upon turning it on, I see the zones from my primary DNS. does this mean it set itself up to backup. Since I am not sure how the zones got there, I want to delete them to start over, do you see any danger in deleting the zones of my second DC and recreating the zones all over again as secondarys.
