configuring DNS server
Posted on 2004-04-30
I am in a bit of confusion.
I have 3 servers all as domain controllers.e.g DC1 , DC2 , DC3.
Dc1 is the first Dc and it is the global catalog server , DNS server .
This server is also our exchange server.As i want to decrease the load on this machine , i want to transfer the DNS services to other machines.
So i installed DC2 and DC3.I want both server to have DNS.
How can i install the DC2 and DC3 to work as primary and just like backup DNS and DHCP.Although there is nothing like backup BDC in windows 2000 but just as a fault tolerance is it possible.I know it is but not exactly.
Q1. I installed the DCPROMO (active Directory on both DC2 and DC3)after installing the Dns service on both server i could see in the DNS - all the four folders udp , tcp etc... so it means as the DNs is active directory i tegrated ...the DNS copied all the contents .Will it work?
Q2.What will happen if i will remove the DC1 which is the source DNS lets say.
Q3.Lets say if i will delete the Dc1 and will use DC2 as the DNs , how about the forwarders and the clients.the clients are getting dynamic IP address.What settings i need to put on this DNS server and how about the IP address of ISP ?
Q4.Important: HOw about if i will enable the same DNS service on DC3 also it will copy the DNs records and what about the IP address in the TCP/IP settings.where i will put the DNS ip of ISP and i want this server to work lets say when DC2 doesnt work just like people can still connect to the internet with DC3 individually and vice - versa for Dc2.In future i will not be using Dc1 (only Dc2 and DC3) .
