After upgrading a Windows 2003 Server to Windows 2012 Server for a client, the Canon iR C2550 would not scan to the new folder which was configured in the same way as the original server. Now the server name was different and so that should have been the only change needed. So why didn't it work. So this is what we did to troubleshoot the issue.
1. DNS - In this case we had to go back to the original DNS configuration and update the DNS to point to the new server since its IP address had changed.
