We have an issue with our inhouse DNS. We have one server that is not a DC,
it is a domain member however. We have clients that will have no issue
connecting to this server and then all of sudden they can not connect.
Instead the client will be redirected to our main DC that host the GC. If
we flush DNS on the client or restart the client it will connect again fine.
It is very sporadic, and will happen on one machine one day and a different
machine another day. I checked all DNS settings on our server and they
look correct. I even took them out and put them in Manually once, another
time I deleted them and ran ipconfig /registerdns on the server that we can
not connect to and it seemed to register correctly. Can anyone shead some
light on what the heck this may be?
 
This is not really a group policy issue - meaning you could have been
more judicious in your choice of cross-posted newsgroups.
Perhaps a post only to microsoft.public.windows.server.dns ???

Anyway, when you said
If we flush DNS on the client or restart the client it will connect again
fine.

indicates that the client has been given an invalid IP since flushing the
client will not change its current in-use DNS server (for that use
net stop dnscache / net start dnscache). Hence, your question is how
did the client cache get poisoned?
