DNS considerations when adding a 2nd and 3rd DC to a domain upgraded from windows nt 4.0
Posted on 2004-08-13
I'm upgrading a domain from NT 4.0 to windows 2000. I've already upgraded a new NT 4.0 PDC to w2k Active directory. Now I want to add another DC or 2 DCs for redundancy and take the upgraded machine off the network. The upgraded PDC has DNS running on it and I would just assume to set up DNS on the 2nd and 3rd DCs, but I'm not sure of the options I would choose when I run dcpromo and setup DNS on the next 2 controllers which will succeed the upgraded box. Please feel free to tell me what for you might seem obvious. For example would one DNS server be a client of another? Also, I'm not sure whether it is important to mention but we don't use DHCP on our network.
