Can you suggest what the recommended DNS configuration would be for the following network please (current config. in brackets)
DC - Windows 2012 R2 Server (this is currently the ONLY DNS server on the network - configured with it's own internal IP address only, no secondary DNS)
BDC - Windows 2008 (configured with the IP address of the DC as it's only DNS server, no secondary)
Member Server - Windows 2003 (configured with the IP address of the DC as it's only DNS server, no secondary)
Client computers - Win7 and XP - currently configured with DC IP address as their only DNS entry, no secondary.
Questions - 1. What's the optimal config. for each 2. Is it essential to have a second internal DNS server configured, i.e. should the BDC have DNS installed also?
Thanks in advance
