wntChgPswd behavior different between W2K and NT4
Keywords: wntChgPswd behavior different between W2K and NT4
Question:
When I use:
wntChgPswd("", username, oldPassword, newPassword)
on a Windows 2000 workstation, the new password is effective immediately. That is, after I run a winbatch program with this command to change the password, then do a Ctrl-Alt-Del to lock the PC then a Ctrl-Alt-Del to unlock PC, the new password is accepted.
I then log out of this workstation.
If I run the SAME program using the SAME username that authenticates to the SAME domain, but this time use a Windows NT 4 workstation, the new password is NOT effective immediately. That is, after I run the program to change the password, then do a Ctrl-Alt-Del to lock the PC then a Ctrl-Alt-Del to unlock PC, the new password is NOT accepted. I still have to use the old password. The new password is not accepted until I log out of the workstation and log back in.
Curiously, if I do not use the Winbatch program to change my password and just use the Ctrl-Alt-Del method on the Windows NT 4 workstation, the new password DOES take affect immediately.
Is this expected behavior? Or am I missing something?
Thanks for your help in advance.
Answer:
We just use the standard API's to do this. One of the improvements in WIndows 2000 is how that API works, and that have managed to make it work immediately.In Windows 2000 the API has an extra parameter or flag called "UpdateCachedLogonCredentials" that is not available in the Windows NT version of the same api.. hence the different behaviour.
