Hello. I have a Canon MF8450 on my network, which used to scan documents and store them on the local server using SMB. It suddenly stopped working, the Canon device can't find the SMB server. I suspect Windows update/autoconfiguration change might be at fault, but I am not sure. I have tried doing this : https://support.microsoft.com/en-us/kb/2696547 disabling SMBv2, SMBv3, enabling SMBv1, and the same with v2, but with no success. The server is running Windows Server 2008 R2. I have captured packets from/to the Canon, when it's trying to find the SMB share, maybe that could help. Canon IP is 192.168.1.30 and the server IP is 192.168.1.3 : Dropbox link How could I make SMB work again?
