help with domains set-up

I have two win2003 PDC's, each (obviously) a seperate domain. I want to create a trust relationship between them but neither of them seem to be able to see the other one! I know very little about domains, and this is to test a problem from a customer site.

Am I allowed to do what I'm trying to do? What I want to be able to do is run our software on one domain, authenticating from the other one. I'm assuming I will need a trust between them?

Any help would be very very much appreciated, or any pointers to useful doco?

Thanks

Chris

 

Hi chrisgeorge,
The first thing that comes to mind is to check the IP addresses, to see if they match. Try to ping one server from the other. If you can't, then there's your problem. If the ping test fials, try pining each server from a machine in that domain. If one (or boht) of those ping tests fails, your problem is likely a faulty network card

 

If you are using the 2003 domain controllers in their native mode (AD) then you won't have PDC/BDC but only DCs. Those of us who started out with classic NT domains have some unlearning to do.

If the two domains are on different networks, the ping testing recommended will tell you some very useful information assuming the hardware tests good so that you can ping a device on the same network but not on the other one. That would point to a router issue - probably no route set up from one network to the other.

Not that all members of a domain need to be on the same network because they certainly do not but just that different domains are almost never located on the same network.
