Its my own fault, I've upgraded from Samba version 3 to version 4. It told me there were config differences when I updated, I reviewed them and they 'appeared' like there was no major changes.
However, for some unknown reason I've now lost access to my shares and I'm struggling to identify the cause of the problem to resolve it.
Could someone provide me with some guidance? I've checked logs and smbstatus, I get actual error messages but I don't know how to solve them.
Code:

Some of the info I found when reading logs appeared to be with CUPS/Printing. Of which I have non connected, or do i want to print/it be a print server.

I have re-done my smbpassword (sudo smbpasswd -a adam) and ensured that it matches what I had before.
I'm sure its an authentication issue of some kind that's different between 3 and 4.
Any guidance would be very welcomed.
attempted to attach smb.conf to post but it said it was an invalid type so I've pasted it below.
Code:
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
# - When such options are commented with ";", the proposed setting
# differs from the default Samba behaviour
# - When commented with "#", the proposed setting is the default
# behaviour of Samba but the option is considered important
# enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
