I have an issue where I am trying to get a Dell 3115CN MFP to scan to a file server from a satellite office to the main office.

There is a VPN at the router level that is working as there are network drives attached to the users account on login over the domain. I can also ping the server through IP and computer name.

The networking on the printer is working as I am able to scan to email.

The computers are running Windows 7 Pro and the File Server is Windows Server 2012.

The settings for the scan go in without issue, when I attempt to make a scan over the network to the server I get a 016-780 Login error. I have used several different accounts, 2 that were created for just this purpose, the domain admin account, and a standard user account.

The printer is accessible by the file server in the main office.

Main Office: File Server

Satellite Office: Dell 3115CN MFP
