Joining a AD SSO domain fails for a UTM on W2K12 domain controller if SMB protocol (1.0) is not installed. In this case the SMB negotiate request will be refused from DC.
By default a minimum of SMB 2.0 is required for Windows Server 2012. As the UTM talks SMB 1.0 we are not able to join the domain.
