The server is configured as CLASSIC PRIMARY DOMAIN CONTROLLER with openldap backend. I have about 3000 clients connecting. almost all are not in domain (heterogeneous workgroups).

Go to the Acer notebook and turn off the Guest user.

Can I also suggest that you start making plans to upgrade to AD, SMBv1 
is going away and a PDC must use SMBv1.
