We are about to upgrade a small (50 users) NT4 domain to Win2k3 AD. We currently have one NT4 DNS server. We are a small company with two locations - Home Office and a Disaster Recovery Site. We are unsure if we should use the AD Integrated DNS or use non AD integrated DNS. Are there good points and bad points to integrated vs. non integrated? We are planning to have two AD servers in the home office and at least one DNS server there. At the DR Site we are planning for one AD server and one DNS server. If the DNS is integrated will that be too much data to pass through a VPN connection between the two sites? Any links to helpful white papers, articles etc would be appreciated. I am a novice so I am learning as I go. Thanks! -Caryn
