I recently ran into an issue with SMB scanning on a Konica/Minolta Bizhub to a Windows 2008 R2 server. I wrote up instructions how I resolved it at http://blog.korteksolutions.com/how-to-setup-smb-scanning-on-the-konica-minolta-bizhub-copier-to-scan-to-a-windows-share/Hope this helps!
so whats the fix well FTP works or using a File server such as a Nas drive many Nas drives will allow scan to folder as well eg the D-Link DNS 325then the admin of this can be controlled but Microsoft needs to sort this if they want windows 8 in the office ...
