Hi cdhodgdon,
Thank you for using the Support Forum.Please take a look at the recently published support article SMB Workflow Scanning Fails With "Login Failure, Check User Name and/or Setups" Message from the online support for your product. If none of the solutions offered in the article work for you please consider contacting your support centre for further assistance.
I am working with a client of mine that has a WorkCentre 7830. His office has 5 computers in it all running Window 10 Pro 64bit.
Up until recently the Workflow Scanning worked on all the computers. Each user/computer had their own template and name in the system and they clicked it and everything would scan to the folder on that computer no problem.
Recently two of the computer now fail. It gives a Login Failre. Check user password and/or setups. I have re-entered the password, deleted the template and created a new one with all the correct information, heck I have even created a brand new user and it still fails. Turned off firewall, turned it on, added custom rules for port 445. Nothing seems to work, please help.
