HI, this is has nothing to do with Samba, it's a windows thing. If you 
look here:


Under the heading 'NetBIOS domain names' (note this is another name for 
'workgroup'), you will find this:

Names can contain a period (.). However, the name cannot start with a 
period. The use of non-DNS names with periods is allowed in Microsoft 
Windows NT. However, periods should not be used in Active Directory 
domains. If you are upgrading a domain whose NetBIOS name contains a 
period, change the name by migrating the domain to a new domain 
structure. Do not use periods in new NetBIOS domain names.

This problem has come up before, it may be that Microsoft has tightened 
up on the use of the dot '.' with windows 10.
