I can no longer scan to a folder or access shared folders on the network of a Windows 7 PC. Apparently, SMB1 is disabled but when I went to "Turn Windows features on or off" and looked for the SMB 1.0 CIFS Client, it wasn't listed. I also checked the Registry (Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters) and SMB1 was enabled. Is there somewhere else that it can be re-enabled? I also checked for the update KB4480970 released on Jan 8, 2019, which caused loss to shared folders on Windows 7 PC's and it wasn't installed either.
Any help would be much appreciated.
