Dear Ricky, 

Yes, in my original post, below, I gave some details about smb.conf, but
to summarize: 

 	* I am using Samba 4.1.11.
 	* server role = classic primary domain controller
 	* domain logons = yes
 	* domain master = yes
 	* When I define a fixed-name as logon script in smb.conf, it works :
 	* logon script = employee.bat
 	* But if I try either %g.bat or %G.bat, or even "%G.bat", it doesn't
work :
 	* logon script = %g.bat
 	* logon script = %G.bat
 	* logon script = "%G.bat"

I can give more details, now: 

	* 

I tried this, which proves that while only %U is working, all others
(%G, %g, %u) are broken :
logon script = %G%g%U%u.bat
And the associated logs :
