Password Please?

The PWDMan tool can help make changing the password settings on multiple systems a breeze.

Do you remember the last time you changed your administrator password? How about all the time it takes to change password settings on 10, 100 or 500 systems? You know how important it is to remind your users to change their passwords, but one of the most common -- and commonly overlooked -- administrative tasks is changing the local administrator account on domain member desktops and servers.

Fortunately, you can do this easily with VBScript and ADSI. Not comfortable with scripting? Never fear. I've wrapped up all the functionality you'll need in an HTA called PWDMan. It only requires that you have remote administrative access and Windows XP. (The tool will run on Windows 2000, but you'll lose a few features.)

With PWDMan, you can query a single computer or a list of computers to determine the age of the local administrator account's password to see if it's time for a change. In the drop down box, enter either the name of a computer or the name of a text file with a list of computer names. Be sure to include the full path if it's not in the same directory as PWDMan. You can also click the "Browse" button to find the text file.

If you're following security best practices, you've renamed the local administrator account. If so, change the name of the account under Account Information. PWDMan will check the password age of the specified account on all computers in your list. You don't need to actually enter any passwords until you're ready to change them.

Ready to Run
PWDMan has two runtime options. You can verify that the computer is indeed up and running first with a ping before you try to change anything. This feature uses the Win32_PingStatus class (which is unavailable in Windows 2000).

You can also create a text list of any computer that fails. This helps you go back later and manually check those machines to see why the change didn't take. PWDMan creates a log file with a unique name using a time stamp in the same directory as PWDMan. When you're ready, select "Report Only," click the "Go" button, then sit back and watch. PWDMan will display its progress and create a simple report that you can print or export to a .CSV file.

When you're ready to actually change the password, select that option. Enter and confirm the new password. PWDMan will mask the password, but because you're making such a major change to your network, PWDMan has a "Show Password" button you can use for a sanity check before you pull the trigger.

When you click "Go," it will warn you of the potential risks of changing passwords. Take a few deep breaths and make absolutely certain you're ready to change. As with anything that makes changes to your network, you should first test it thoroughly in a non-production environment.

Assuming you're ready, PWDMan will then go out and touch every computer in the list and change the password for the specified account. The tool will then display the results of the change. You've just accomplished a tedious -- but critical -- task in minutes instead of hours or days.
