>I found something disturbing today.  I installed SP6 on an NT4 SP5 server
>that I've been using as a PPTP client for the past couple of years.  After
>installing SP6, I found that the setting for saving passwords for at least
>PPTP dial-up has been enabled which is a feature I never, never use.  While
>this is bad, the disturbing part revealed by installing SP6 is that even
>though I never used the "Save password" feature with PPTP, my password was
>in fact being cached.  I know this because the first four PPTP dial-up
>connections I tried (i.e. four different PPTP servers) all immediately
>connected and authenticated without prompting me for credentials.  Two
>others failed to connect immediately because the cached password did not
>match the current password for my domain account.

>If any of you get a chance, could you pls verify this behavior.
