Then you presumably created a Domain (DCPromo the first DC) and
chose "VALLEY" as you domain name. This auto-created the VALLEY
zone as a single label domain name.
If so, it will not be difficult to change and manage correctly.
Google for:
[ site:microsoft.com single label DNS name dynamic ]
You can add "2000" or "2003" depending on your Server version.

++++Thank you, I will try that.

You cannot mix two different "sets" of DNS server; you cannot bypass the
internal DNS even with an alternate. When the alternate goes active the
internal DNS and domain resources will become unavailable.


+++So are you telling me that those systems that are not authenticating on
the domain, and are simply standalone are causing an alternate set of
settings to go out to the workstations? It makes sense now.

I think you MAY understand it so allow me to clarify: The settings don't
"go out" to the client, but if the client queries a DNS server which cannot
resolve "internal names" (e.g., the ISP or some firewall/gateway DNS
that isn't part of the interal DNS server set) then the client will receive
a NEGATIVE response and thus fail to find the internal resources.

IF that is what you meant above, then you do understand.

Yes, I believe I understand now.


Is this an AD domain or not?

Machines must use a default gateway ON the same subnet (broadcast domain)
to which they are connected.

Are there machines connected to the server which is then connected to the
gateway router?

ISP -- Gateway -- (machines) -- Server -- (more machines)

+++ IPS - DSL Modem - Router (4 port) - 24 port Switch - machines and
server
on same switch

Ok, but look at two issues of being unspecific above: "Switch"* can either
be
a bridge type switch (layer 2) which does NOT separate "broadcast domains"
or a Router-Switch (layer 3) which DOES create separate broadcast domains.
(In fact some are both, and even configurable VLAN switches which is even
more complex to explain, but follow the same simple rules once configured.)

The router is a simple Linksys 4 port Router, the switch is a basic switch,
not managed if that helps.


Second issue is that TWO-NIC server. Is it a router?

I put a second NIC in the server as I understood that I could access
remotely without it. Is there a recommended setup I could use so that I
could remotely access using only one NIC?


If not, why does it have 2-NICs?

You have between 1 and 3+ subnets based on the unspecified number of
routers present above.

*Switch when used out of context is a very imprecise term. Router and
bridge have very precise meanings in almost all cases.
