SYMPTOMS
When you use the Dial-Up Networking client software for Microsoft RAS to connect to a server, a dialogue box requests the user's User ID and password for the server. In the same dialogue box is the Save Password check box, which is intended to provide the user with the option to cache their security credentials if desired. However, the implemented client functionality actually caches the user's credentials regardless of whether the check box is selected or not.

MORE INFORMATION
For information on this problem using Microsoft Routing and Remote Access Server (RRAS) as a Dial-Up Networking client, please see the following article in the Microsoft Knowledge Base:
233303 DUN Credentials Cached When Save Password Not Selected with RRAS
Cached security credentials, including passwords, are stored and encrypted in the registry and protected by an access control list (ACL). RAS uses Local Security Authority (LSA) Secrets to store the entries. The default ACL values only allow administrators and the user associated with the credentials to gain access to these registry entries.
Additional encryption for LSA Secrets is available to provide protection for this information when stored on backup tapes, the Emergency Repair Disk, or other registry backups using the System Key option. For information on System Key (Syskey.exe) functionality, please refer to the following article in the Microsoft Knowledge Base:
