zones

I have 10 zones on a private Active Directory with 2 DCs with DNS services on each DC. I want 9 of the zones to answer querys local and if not query zone 10 that has 2 servers configured to forward to a external DNS server. All zones are intergrated in Active Directory. All connections are connected by T1s. My question is 1. is this two many DNS servers. 2. should I just place the 2 IPs of the DCs that forward to the external in the forwarding properties "non recursive" or should I make a round robin starting with dns server 1 forwarding to 2, 2 to 3 etc?

You are confused. "zones" don't query other "zones". "zones" are not active
entities. They are subdivisions of the overall DNS database.

It is _servers_ (in particular, proxy servers) that query other _servers_.
And since you tell us that you have only two of them, designing how they
intercommunicate would seem to be quite straightforward.

Sounds like you need conditional forwarding. What Jonathan said hold true
also, is that one zone will not query another zone. Servers query other
servers. But if you want a specific zone to be queried by a specific server,
conditional forwarding will do that.

Create the 9 zones on the machine. That machine will ALWAYS answer those
queries to those zones since it is SOA of those zones. A DNS server WILL NOT
forward a query for what zones are created on itself (what it is SOA for).

Use a conditional forwarder to query any requests for the other zone. Just
dont create it on this DNS server or it will never forward it.
My question is
1. is this two many DNS servers.

I don't understand this statement above? Is it a typo?
2. should I just place the 2 IPs of the DCs that
forward to the external in the forwarding properties "non recursive"
or should I make a round robin starting with dns server 1 forwarding
to 2, 2 to 3 etc?

See, now I'm getting confused with what you;re trying to do here. Any
servers in the forwarding tab will be queried if the local DNS cannot
resolve it. Stopping recursive wil stop it from using the Roots. If the
machine you are tyring to forward to is not an ISP's DNS and you want to
keep it private, then this is one method.
