[Samba] Cannot start SMB on CentOS 7

[gw1500]

*I am running Samba on CentOS 7 and for some reason I cannot get the smb
daemon to start (Samba version 4.9.1). This is the status after a failed
start:*

smb.service - Samba SMB Daemon
???? Loaded: loaded (/usr/lib/systemd/system/smb.service; enabled; vendor
preset: disabled)

*I cannot find anything in my searches that seems to relate to this
specific problem. FWIW, here is my config:*

[global]
?????????????? workgroup = DAPWG1
?????????????? security = user

?????????????? passdb backend = *****

?????????????? printing = cups
?????????????? printcap name = cups
?????????????? load printers = yes
?????????????? cups options = raw

[homes]
?????????????? comment = Home Directories
?????????????? valid users = %S, %D%w%S
?????????????? browseable = No
?????????????? read only = No
?????????????? inherit acls = Yes

[printers]
?????????????? comment = All Printers
?????????????? path = /var/tmp
?????????????? printable = Yes
?????????????? create mask = 0600
?????????????? browseable = Yes

[print$]
?????????????? comment = Printer Drivers
?????????????? path = /var/lib/samba/drivers
?????????????? write list = root
?????????????? create mask = 0664
?????????????? directory mask = 0775

# Web directory access
[webdir]
?????????????? valid users = dap, at apache
?????????????? writeable = yes
?????????????? browsable = yes
?????????????? path = /var/www
?????????????? hosts allow = 192.168.0.0/255.255.255.0

# ftp directory access
[ftp]
?????????????? valid users = dap, at apache
?????????????? writeable = yes
?????????????? browsable = yes
?????????????? path = /var/ftp
?????????????? hosts allow = 192.168.0.0/255.255.255.0

*Can someone help me debug this. At one point Samba was working but I
don't know what changed other than perhaps a CentOS 7 update. TIA.*
