If either computer is running Windows NT or Windows 2000, it must also be running Windows Services for UNIX 2.0.

  • To use the tlntadmn command, you must log on to the local computer with administrative credentials. To administer a remote computer, you must also provide administrative credentials for the remote computer. You can do so by logging on to the local computer with an account that has administrative credentials for both the local computer and the remote computer. If you cannot use this method, you can use the -u and -p parameters to provide administrative credentials for the remote computer.
