two domains on same network won't talk


I have 2 domain controllers on my network.  (One was inherited and is only temporary.)  Both have DNS, active Directory in use.  I need to be able to make these 2 domains coexist.  What is the best route?  The problem it is causing is one domain has an application that we still need to access.  I need this application to run while I'm logged into either domain.  Right now, it will not.

So you have two domain controllers, but they are two different domains?   Are the domains in the same forest. Is it a parent/child or just two separate domains.

Is there a trust between the two domains?

Not linked, at all.  2 completely separate domains.  No trust.

You will need to setup a trust if you want to share resources between the two.

Yip, definitely will need the trust in order to assign permissions to a user in Domain A to resources in Domain B.
You'll also need to look at Domain Local groups and possibly converting some of your existing groups.
