Server Message Block (SMB) communication with products prdating Windows°NT® Server°4.0 is no longer supported in Windows® 7.
Some printers and scanners may only support the pre Windows°NT Server°4.0 RAP protocol to enumerate shares. Support for the RAP protocol has been mostly eliminated. A network-connected scanner may not find the shared folder in your computer. As a result, you cannot transfer the scanned data to your computer. This happens when the Scanner device does not support either SMB2.0 or [MS-SRVS] Server service RPC over named pipes. This behavior is by design.
For more information on SMB behavior in Windows Server® 2008 R2, see 6 Appendix A: Product Behavior in the MSDN Library (http://go.microsoft.com/fwlink/?LinkId=165775).
