[CentOS] Samba won't start on Centos 7.3.1611

Hi folks,

I've been googling for an hour on this which seems to be awfully
basic.  But I cannot find anything definitive.

[root at centos-gig ~]# systemctl enable smb.service
Failed to execute operation: Access denied
[root at centos-gig ~]# setenforce 0
[root at centos-gig ~]# systemctl enable smb.service
Failed to execute operation: No such file or directory

Have tried things like :
chcon -t samba_share_t /home/amckay

Also took the output from:
getsebool -a | grep samba

and set all them to "on"

Stripped my config down to the most basic.

What am I missing?
