DNS Issues (rapid responses appreciated)

[Guest]

We have a DNS server in multiple buildings throughout our WAN, and now found something peculiar. When we do a ping to the root of the domain at different times, it points to different DNS servers or DC's within our WAN. Why is that

Also we recently removed a DNS while maintaining 2 others that are the GC and a DC, yet our domain started to die out in the world. Both of the other DNS's were listed as NS records at the parent servers, so we are wondering why when we removed the DNS it didn't failover to the other two?

Appreciate any rapid response to this

Just a shot in the dark here..

Have you got Dynamic Updates set to "Yes"? Have you set Forwarding
correctly on each DNS??
