Scanning documents using your Xerox multifunction device (MFD) to a server uses the Microsoft Server Message Block (SMB) protocol. There are several versions of the SMB protocol. The SMB protocol used for scanning is negotiated between your server and Xerox device. Generally the highest version that both the server and the Xerox device support will be used. But it is possible to disable lower versions of SMB by configuring the changes on the server.
