Recently I enabled the Firewall in XP LAN connection and
notice that most times user cannot change their
passwords. They will receive "The system cannot change
your password now because the domain yyyy is not
available.". Our server is running NT 4.

I found on the Knowledge-based article 324141 which is not
true in my case.

This is what happen. The users logged in and received a
prompt telling them that their passwords will expire in 14
days. So when they choose to change their password now,
typed in the new password, then the above prompt appears.
However, they are not the same as article 324141 where the
password expired and the system has locked the users out.

Am I missing something? anyone knows what I can do here?
Do I have to apply a patch to the NT4 server to allow
connection from a Firewalled XP LAN connection? Thank you.
