SMB Scan from MFP Fails to Access Share on Server 2003

I have an mfp that can perform smb scanning to any xp or 7 workstation in the network.  I need it to scan to the 2003 server but it won't go.  I have checked over the sharing permissions and smb user setup on the mfp 1000 times.  I installed wireshark at the server and the mfp attempts to send the job but the server authenticates the AD user configured in the mfp but denies access to the shared directory.  I have attached the text file exported from wireshark.  If anyone actually has wireshark installed and wants the actual capture file I can provide that as well (they're easier to look at then the text file).

Chances are the MFC uses the more primitive authentication style for SMB.  It is like a Windows 98 endpoint.

You might need to disable the SMB signing of 2003 server to make it work.

By default, SMB signing is required for incoming SMB sessions on Windows Server 2003-based domain controllers.  Is it a domain controller?

Also, you might need to disable or tweak NTLMv2 Authentication:

You might want to see if the MFC vendor has any ideas or firmware upgrades.

This looks like it could be just what I need.  The server response was 15 which indicates that signing is required by the server (according to the ms article).  I will be back at this office tomorrow afternoon and will test these solutions and report back.  Thanks a bunch.

Success!  This is a well deserved 500 points.  All I had to do was turn off the required smb signing.  Didn't have to mess with NTLMv2.
