I'm replacing an old computer that is running Windows 7 and WinDNC v5.2.

And setup a new computer running Windows 10 and WinDNC v6.02.

Everything is setup identically as far as I can tell. The W10 machine can see the router and communicate with it. (Through a serial port)
However, on the Router when trying to access a network directory (G:\...\) I get an error saying. "Error: Accessing Disk"

Is there something obvious I'm missing? A setting on the router that needs to be changed or...?

Thanks for reading!

If you need any more information ask away.
