Help with event 1002: The DNS server being queried for interface has changed

We are regularly receiving event 1002 below advising the DNS server being queried for interface EXT has changed to 10.1.1.250.  10.1.1.250 is our alternate DNS.  Does this event indicate that the client has failed over to to our alternate DNS for all requests, or does it mean it could not find an entry for a single address and is checking the alternate?

Event 1002
We don't see an entry in the log for when the DNS changes back to the primary, but using nslookup we see it does.

Windows DNS does try the second unless it gets No RESPONSES from the first. It will never say well A didn't know about it so I'll try B.
B is only used in the case that an attempt to query A times out or is refused.

Thanks Neilsr.

I'm still a bit confused on what Event 1002 conveys.  Does it mean that server 10.1.1.250 (the alternate) is being referenced for this single DNS lookup or does it mean that it can't communicate with the Primary so it's using 10.1.1.250 for all future DNS lookup calls?

Not for all future no. It could not talk to the master on that request so switched.

Just for that single lookup?  Ie the very next lookup will try to connect to the primary DNS first?
