I have a Windows 7 computer that I am using as a "gateway" between two otherwise isolated networks (network-A and network-B). I have another computer on network-A with a shared drive titled "Media Drive". I have mapped the "Media Drive" on the "Gateway" computer (no Problems).
I want to be able to share the "Media Drive" on the "gateway" computer so that a computer on network-B is able to access the drive as if it were located on the "gateway" computer. The option to share the mapped drive, "Media Drive", is missing. From a computer on network-B, I can access the shared local disk on the "gateway" computer (as a test).
