Password Challenge/Response install

I have two Netware 6.5 sp3 servers. My PCs are Win XP, sp2.

We have decided to start using the feature self service password. I am
running into issues.

1) If I allow a user to reset their password. The user can change their
NDS password without problem, but the local NT password does not get
updated. I then run into the dreaded unsyncronized NDS\WinXP password
problem.

2) I then tried to just use the "password hint" option. While I can pass
the challenge quiestions, NDS tells me no hint is defined. How do I setup
the hints.

thanks
