adding a 3rd domain controller (different domain) to 1 network.

Hi,
We gave 1 of our offices for rent to an escrow company and they moved in with their equipment and they will be connecting to our current network.

Our equipment: 1 domain, 2 domain controllers with active directory etc.
we are all running static ip's

Theirs: 1 domain controller with active directory etc.
Their server was running static but workstations were DHCP.

we do not need to sharing capabilities with eachother and security is not of concern.

my question is, what would be the proper way to setup their 1 windows 2003 box and their worstations.

Should i assign them our static IP's and of course our gateway? what do i assign the DNS? to their server and workstations?

Demoting their DC is not an option , i need to leave it as is.

What would happen if i assigned their DC our DNS IP's?

Thanks

Its not ideal - but you can to this.

All their machines MUST point to their DC and to that DC ONLY for DNS. Their DC also should point to itself for DNS. The default gatway (router) for all the machines needs to point tou your router. Their Server needs to be configured with DNS forwarders that point to your ISPs DNS servers
