Hi anodos,
So I increased the logging level on samba & then tried to connect to my filer. Below are the results from log.smbd first showing me connecting to the filer by clicking on the host in the "Network" part of Windows Explorer and then connecting via IP (\\10.56.56.2 ).
Code:
[root@filer] /var/log/samba4# tail -f log.smbd
