SMB Button Disabled - OS 6.7.4

You'll have to forgive me as I am not very technically proficient with this.

OOMing?  I have googled it and whilst it gives a very basic explanation, not sure what would be causing this.

To recap what I have done so far: :

- updated the os to 6.7.5;

- disabled all quotas (were never loaded to begin with);

- uninstalled all apps and stopped anti-virus;

- closed down all the services I could;

- removed all account permissions and re-loaded them;

- disabled cloud access;

- confirmed no backup services running (never was setup);

and still cannot activate SMB.  Sometimes, the green light will illuminate but then disappear a few seconds later.  

Not sure if this is relevant but I was reviewing some of the entries in the log files and found this buried in the 'systemd-journal' file.

Is this related to what I am experiencing?

I have gone through all settings and could not locate anything obvious.  However, as mentoned eariler, I am not very confident with this device.

Not sure where to go from here.  Do you think a Factory Reset would resolve this?  Its the last preference considering the amount of time (and expense) needed to back up everything but I need to get this running again.

Any assistance provided is always greatly appreciated.

Thank you
