Subneting help

[davomarti]

I have 2 Win2k(domain and web) servers and 5 WinXP workstations on a
subnet(192.168.10.xxx, 255.255.255.0) connected to a Linksys DSL router. I have the
router WAN port connected to the internet.

We have a group of other Windows computers that we want to access using
above computers. The IP's of these computers are 10.40.xxx.xxx,
255.255.0.0. These computers are not connected to a router. They're just
on a LAN. We don't want to mess with the ip's of these computers.

How can I access these computers? Do I need another router? If yes, how do
I connect the two routers?

Thanks!!!
Dave

I suggest to change the IPs, is cheaper, easier if you have DHCP enable. Now I need an answer. I know how to join PCs on the domain, NT, 2K and XP, but I have a small problem. I do not how to configure 2 PCs so they can talk to each other. If I had a server I can set it so it will give IPs thru DHCP. My question is and might sound stupid, how can you set a workgroup so they can talk to each other. If you see on my post PING...! is all explained. Help please.
