Using multiple home network routers

I have 3 routers connected due to the different locations of my computers. 1 of those being from my ISP. I have 2 servers on these networks 2 laptops, and two desktops.

Anyway for some reason, one of my servers (Windows 2000) and my desktop (Windows 7) both on the same router which is just being used as a switch, DHCP disabled have a communication issue. When they both traceroute, they go external of my network through the isp just to come back and find one another.

I don't have this problem with any other machine. I have a laptop and a server (Windows 2003) on my other router which has DHCP enabled. When i traceroute to either one of the other machines I get a direct 1 HOP.

My only issue is when these to machines attempt to connect to one another. This also causes other issues like 'Trusts'.

What could be the problem?
 
Do an ipconfig on both machines and make sure they are in the same range.

I am guessing one of the 3 routers has DHCP enabled. Or you have a static IP on the machines with an incorrect gateway.

Otherwise, unless you have static routes defined in the router I don't see why it would be going external.
 
Another question.

Are all these routers actually acting as routers? ie, are you NAT'ing between them? If they are all trying to talk to one another I would turn the routing functions off and use as dumb switches / access points.

I would also use the Server 2003 box as a DHCP server as it will give you more control on DHCP options for defining correct gateway's etc.
