[Samba] Can't connect anymore a share in domain A from domain B since

[L.P.H. van Belle]

Try it like this. 

net use z: \\<computer in A.FQDN\<share> /USER:NTDOM\%username% 

Does that work for the samba 4.1, if not, check if you windows disabled smbv1 
See: 
https://support.microsoft.com/en-us/help/4034314/smbv1-is-not-installed-by-default-in-windows

Best is, upgrade you systems so you can use samba 4.7+
