We recently rebuilt a machine from Windows 2003 to Windows 2012 R2. Workflow scanning was working fine before on 2003 but now on 2012 R2 we get the job deleted and Login Failure. We used the original share (xeroxscans), copied back same E: partition. Gave the xeroxscans account Full Control on both Sharing and Security with rights down into the subfolders. I upgraded the firmware on the 7545 to System Software Version 061.121.224.18803 and verified that SMB1, SMB2, SMB3 are both running on the server via PowrShell. Tried changing to port 445, and I've tried Reseting the Software on the the machine itself. Firewall is turned off.
I've been utilizing everything on this for troubleshooting and other ideas found on the knowledgebases. http://www.support.xerox.com/support/workcentre-7545-7556/support/enus.html?objGUID=5331
I'm at a loss as to what else to try now.
