I have a Canon ImageRuner Advance 6065 that has been scanning via SMB and email since it was installed about 9 months ago. For the past month the SMB scanning will randomly stop working. With a reboot of the machine it will work again. This happens every day. While the SMB is down you can still scan to email and print just fine. When its working I can browse out and find network folders, when its down it can't find anything. Also, when its down, from the machine I can successfully ping the server that we are scanning to, all DNS servers, Gateway. The SMTP server is using a name for the exchange server so I know DNS is working. All of their SMB scanning is directed at one server so i set up another scan folder on a workstation. When it stops working you cannot scan to the server or workstation. I couldn't even scan to directly to my laptop when it was in a down state. I have tried putting a basic 5-port switch between the wall and copier as well as changing patch cables. I have cleared MMI and main controller. Reloaded all firmware. I have an appointment with their IT next week to try setting up their server so we can try scanning via FTP. The SMB functionality is controlled on main controller 2 but must go through main controller 1 where the NIC is located. Canon tech support wants me to try replacing these controllers, so that is what I'll be trying today since I can't do anything until next week. I would greatly appreciate any thoughts as I am slowly running out of ideas.
