We have 2 separate networks, each with a different domain. Each network's domain
controllers and servers are in the same physical location. Each network/domain has
its own router and public address. If I connect a port on a switch on one of the
networks (192.168.10.X) with a port on a switch used on the other network
(192.168.150.X), that is behind the router and firewall connections, will the
different networks be able to communicate with each other? (ping, shared folders,
etc.) If I set up a trust relationship between my 2 networks, so that they have the
same forest, would my switch to switch connection work then?

Richard:
From the perspective of inter-subnet/vlan routing, to be able to pass traffic between two vlans, you will need a router.
If the two subnets belong to the same vlan, then hosts on each subnet will be able to communicate amongst themselves using layer-2/MAC addresses.
Example:
Vlan 10
ip address range: 10.10.0.0/23 gives you two subnets.
10.10.0.0/24
10.10.1.0/24.
Hosts on each of these subnets will be able to communicate with each other without the need for a routing engine because they belong to the same vlan. If they didn't, that is when you would need a router/L3 switch for inter-vlan routing.

Thanks Victor. We will try that, and I will post if we were successful.

I'm sure you will be if you follow that paradigm.
Good luck!

You were right, we were able to set this up by changing the 2 domain controllers that we wanted to connect by changing the subnet mask to 255.255.0.0. Then we were able to setup the trusts between them. Thanks for your help!
