Yep! Use the password recovery system. Here's how:
Have both the user.id you need to crack and your certification ID handy.
In Administrator, go to the Configuration tab. Then go to the Tools feature on the right (if it is displayed) or click on the word "Configuration" in the toolbar up top. From either of these choose the "Certification" menu. From it choose "Extract Recovery Password". It will ask for your certification ID and password first, then if successful, will ask for the user.id you need to which you need access. Once it has that, it will display a message window with a case-sensitive alpha-numeric code which acts as an "alternate" to the real password. Write it down.
Next, go to the top toolbar again. Choose FILE--TOOLS--RECOVER ID... At the pop-up window, choose the user.id file whose "alternate" password you have. A smaller window appears. Type in the precise case-sensitive alternate password, and OK it. If it is correct, the computer will then allow you to change the current password to something you can remember. Test your results to make sure the new password works.
