We're planning on adding a new 2003 DC and member server to one of our branch offices. I have Active Directory Integrated DNS setup on the DC, and was wanting to setup a backup DNS server on the member server for redundancy. I do not want to make the member server a DC. I've never had to set this up yet and was wondering if someone can give me some good advice. For 40 users do you think it's worth setting up redundant DNS? I realize I could point the clients to a DNS server over our VPN(as a secondary). Would that be recommended?
Any advice would really be appreciated.
