I have set up NetSUS running on Ubuntu 14.04.5 LTS, but I cannot figure out why I am not able to connect to its SMB share to upload the Netboot image.

I have verified that the firewall on the server is off.
I have double checked the user account.
I have double checked folder permissions are set correctly.
It doesn't even look like its trying to authenticate with the smbuser. But the smb logs are not showing anything and I am stumped.
Config file shows:
[NetBoot] comment = NetBoot path = /srv/NetBoot/NetBootSP0 valid users = smbuser write list = smbuser create mask = 0755 browseable = No
Folder Permissions:
drwxr-xr-x 2 smbuser root 4096 Oct 7 2016 NetBootSP0
