I have 2 networks in remote locations. They are connected via VPN. Network A is xxx.xxx.1.xxx and network B is xxx.xxx.3.xxx. Both networks have a domain controller running Windows server 2008 R2 standard. Both networks have a folder named "shared". The users on network A want access to network B's shared folder and vice versa. All network users on network A have access (mapped drive S:) to their shared folder. The same is true on network B. I need for a user on network A to have access to the shared folder on network B.
