DNS questions in a Windows Server environment
Posted on 2012-09-17
Hi all. I have a whole bunch of questions about DNS (something that I am not very familiar with) so I hope that with the help of ExEx I will be able to learn about this topic and level up :-)
I have a parent domain (company.local) and a child domain (europe.company.local).
I have two Domain Controllers that do (AD/DNS/DHCP/etc) in the company.local domain: svr3.company.local and svr9.company.local.
I also have two Domain Controllers in the europe.company.local domain: svr1.europe.company.local and svr6.europe.company.local
When I do an IPCONFIG /ALL on the four servers I'm not sure that things are configured properly:
1) All four of the DC's return 127.0.0.1 as one of their DNS servers. I presume this means that DNS lookup is occuring on the local machine. However, does it matter if this 127.0.0.1 address is first in the DNS list or last? (Some servers have it first, others last)
2) I am not sure where the second DNS server entry should point. For example, should the second DNS entry on svr1.europe.company.local point to svr6.europe.company.local, or should it point to (svr3/svr9).company.local.
3) Same question for the servers in the company.local domain.. Should the second DNS entry on svr3.company.local point to svr9.company.local or should it point to one of the DC servers in europe.company.local.
Sorry, I'm new to this game and some of my terminology may be wrong. Thanks for reading.
