Last week I was working for a customer. For my work I need to have a look on the OS where the domino server was running on. But nobody could remember the OS Administrator password. So what to do? There is a easy solution:
With the Lotus Domino console you can execute OS/Shell commands. Start the Lotus Domino console on your workstation and enter:
$ net user USERNAME NEWPASSWORD
This will change the password from the username (you would enter Administrator here) immediately.
This works only if your domino server runs as administrator.
