The following are
          common Windows NT error codes that occur when using the Windows NT
          Security realm:
              
                | Error | Meaning | 
              
                | 1326 | The host machine running the security realm does not
                have a trust relationship with the primary domain controller.
                The host machine may not be a member of the domain or the
                domain may not trust the host machine. | 
              
                | 53 | A network error has indicated that the path to the
                primary domain controller could not be located. This error can
                occur if the domain name is misspelled or if the domain name
                is specified rather than the host name of the primary domain
                controller. |
