JSI Tip 0759. Prevent DUN from saving passwords.

While it is convenient to save your password in DUN, it presents a security risk.

To prevent DUN from saving passwords, use Regedt32 to navigate to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\Parameters

Add Value name DisableSavePassword as a type REG_DWORD and set it to 1. DUN will cease to display the Save Password check box and will forget those that were previously saved.
