DnsMachineName: A string that indicates the FQDN of the server.

NbDomainName: A string that indicates the NetBIOS name of the server's domain.

NbMachineName: A string that indicates the NetBIOS machine name of the server.

The following NTLM server configuration variables are internal to the client and impact all authenticated sessions:
