Basically our LAN is connected over the Internet through a Balance One router, which will route local hosts over WAN1 to WAN5 depending on line overflow/fail.
But local hosts will use a local Microsoft DNS Server, which might serve wrong or non-consistent (WAN depending CDN) IP addresses, giving unpredictable results, as at a given time, local host A might DNS query the local server (routed to WAN1), while the host A is routed at the same time to WAN3.
I wonder if is there a way to keep settings, routing and DNS requests consistent.
But we need the local Windows DNS Server for local AD name resolution
Your thoughts? Should I abandon Internet resolution through the local Windows DNS Server and only rely on current-WAN DNS servers?
