Running an application between domains with no trust relationship
We have seperated our environment into two AD domains on two different subnets. We have the need to temporarily open Domain A to allow Domain B to access to an application running on Domain A. Access rules are wide open and can access the server by IP address and all of it's resources. Have put in an entry into the hosts file to resolve the server by name. Can get the application to run, but with a slight glitch - it prints to a shared printer on Domain A that has print software which charges for pages printed. The confirmation box that is supposed to popup to give a total of the job and how many pages does not, but job goes into the queue.
Without knowing how the application works does it appear that a trust is needed between domains even though resources are accessible? Or is it maybe a DNS issue?
