SMB connection to Windows 2008R2 File Server Problem

Question

Hello, I recently migrated a file server from Windows 2003 to Windows 2008R2.  Since the migration, I can no longer use our Canon multi-function printer to scan documents to a network share on the new file server.  The share has Everyone, System
and Authenticated Users set to Full control and the NTFS Security is setup for Everyone to modify.  The connection from the Canon uses SMB using a domain account called jdoe.  
I wondering if the problem is related the the LAN Manger authentication level settings.  On the new file server and domain controllers it's set to Network security: LAN Manager authentication level is set to Send NTLMv2 response only\refuse LM &
NTLM.  I have setup a network capture and hope somebody can help me out with determinging the problem. 
Here is the detals of the Error

Answer 1

It does seem possible that the NTLMv2 authentication level might be affecting things.  So I would give it a try.  It's difficult to troubleshoot from the image, but I beleive there is a flag in the negotiate response that might give you a clue. 
In either case, I think your question would be better served by our networking group, rather than the group that makes the tool.  While we have some general protocol knowledge, we don't have the depth that the experts for each component would have.
If changing that setting doesn't work we can move this thread over to the right place.
Thanks,
Paul
