Domain A (server 2012 R2) is set up with a one way trust to Domain B (server 2008 R2). I have a shared folder on Domain A that users from Domain B need to access. I have added a test user from domain B to the share permissions and the folder ntfs security permissions on Domain A. Anytime I try to access the share from Domain b I get the error: you do not have permission to access \\machine.xyz.local\fileshare.
Conditional forwarders are set up for each domain. I also tried to set up a two way trust and I'm getting the same problem.
