Change VPN (and other Remote Access) passwords remotely?
Here's a theoretical scenario which I've discussed with some friends but none of us can come up with a solution:
A company provides remote support to clients via VPN and Remote Desktop. If an employee leaves the company, it's good practice to change passwords, just in case the former employee uses their knowledge to damage remote computer systems. I realise that an engineer could visit the clients and change the passwords "manually", but is it possible to have them changed "remotely" from the central office, perhaps via a script? I'd suggest having a .txt file (or an Excel spreadsheet) listing the company, current and new passwords and have this accessed by the script.
Is this idea feasible or is there any other way of changing passwords quickly? If the company has 200 clients, it could take a couple of weeks before the passwords are changed and a "rogue" former employee could do a lot of damage within that time.
