Samba failed to start. Samba error running command

Brief description of the problem

Samba will not start. No configuration changes, other than regular updates as released.
I am very unfamiliar with linux. Very novice. Any assistance anyone can provide would be greatly appreciated.

This only occurs from the Services screen. If I start Samba from the Samba configuration screen, Samba starts as expected.

Detailed step by step instructions to reproduce the problem

Starting Samba service, the following error.

Failed to start samba due to a system error: Error running a command. cmd = /usr/bin/systemctl start smb. rc = 1. stdout = [‘’]. stderr = [‘Job for smb.service failed. See “systemctl status smb.service” and “journalctl -xe” for details.’, ‘’]
