Windows XP Pro systems, Windows user names and passwords for network sharing authentication, intranet or proxy domain authentication, runas/savecred, and so on can be managed in the password management of users and Accounts in Control Panel, or you can run controls Keymgr.dll for Management.
These saved user names and passwords are saved in Credentials, protect, under the user directory%appdata%/microsoft. After you delete both directories, you can clear the list of saved passwords by restarting them.
So you can set up batches to add to the user's logoff script:
Copy Code code as follows:
@echo off
Rd "%appdata%/microsoft/credentials"/q/s
Rd "%appdata%/microsoft/protect"/q/s
However, the two directories also hold the password to access the certificate. Use this method with caution, or you will not be able to use a password-added certificate.
