[CentOS] Centos 7 Samba - all shares read only

I few weeks back my server started having a problem where all shares are now 
readonly.  AFAIK nothing has changed except a 'yum update' which was probably 
around the same time.

Everyone still has the shares on their Win7 PC's and can see the contents. 
However, if they try to open a file it opens read only. If the try to create 
a new file (e.g. right click -> New -> Text Document) it says that they don't 
have permission.

I am not seeing anything meaningful in the log files. Can anyone give me a 
clue how to fix this, or at least how to collect getting debug info?

SELinux has been disabled to eliminate that.
