DC1 = Windows 2008 R2, DNS, GC, all 5 FMSO roles, IP = 220.127.116.11, DNS1= 18.104.22.168, DNS2= 22.214.171.124
DC2 = Windows 2003 SP2, Exchange, DNS, GC, IP= 126.96.36.199, DNS1 = 188.8.131.52, DNS2 = empty
DC3 = Windows 2003 SP2, DNS, GC, IP = 184.108.40.206, DNS1 = 220.127.116.11, DNS2 = 18.104.22.168
Is this DNS configuration OK?
What is the recommended DNS configuration in TCP/IP properties of each DC?
(I had a problem this morning that when I started DC1 alone (DC2 and DC3 where offline) DNS service would not start. When DC2, DC3 went online some minutes after, everything when back to normal, and DNS service started sucessfully, that is the reason I prefer to check DNS configuration)
