Configuring DNS and Agteway in a test environment

HI,
here is the senerio:

I am trying to run the MIIS gal sych walk through.   I have 2 servers newly created.  1 server has 2003 server ent, DC, dns,MIIS, exchange 2003.

The other server has 2003 server ent, exchange, DC.
2 total separate forests.

my problem is that I cant get thenm too to talk to each other.

I created an inside lan connection  server 1  172.25.1.5,255.255.0.0,DNS 172.25.1.5

second server  172.25.1.6,255.255.0.0,172.25.1.5


What do I put for the gateway? Would the wrong gateway cause it to not work?
I use my companies gate way which is 172.16.0.2

Im thinking that I cant use that becuase its not on the same subnet.


secondly.

the walk thru says to make 2 primary dns records so the to active ditrectory forests can talk to each other.

connoa.concorop.contoso.com

fabnoa.fabcorp.fabrikam.com


I put these in Primary zones and still cannot get the 2 server to talk to each other. Whwen I try to connect to Fabnoa domain from Connoa which hiosts MIIS, I get server down or cannot find network connection.
Is there anything other than adding them to rpimary zones I need to do?  I have deleted the zones many times and redone it.  Do I need to reload AD so it syncs to it again?

COnfused...

can you ping from both environments?
NJComputerNetworksCommented:
Server 1
IP: 172.25.1.5
Subnet: 255.255.0.0
DNS 172.25.1.5

Second server
IP: 172.25.1.6
Subnet: 255.255.0.0
DNS:  172.25.1.5


Because these servers are on the same network...and the same subnet, a default gateway is NOT needed for the two servers to "talk" to one another.

Adding a gateway of 172.16.0.2 would not work....

The dcdiag test fails on the second server.

I get this.  How can I get the second server to resolved.   What entries must be made in the other server to make this work?
