Thanks, I too thought thay maybe this list was not right, Do you know a
better suited one? There is not much in the Windows world most of the
list are for SAMBA.

My server implementation is a Windows server 2012, How do you know what
version it is using? I cannot see one in the wireshark diessection and
the Windows 7 clients dont seem to have a way to check.  The server
however, now you have prompted me to check does say:
*EnableSMB2Protocol              : False*
