samba - Jul 2003 - Password Must Change and Windows 2000 Clients

This is a Domain Controller question.  I got this email from the samba website
as apparently the ntdomain list has been discontinued.  I apologize if this is
not being sent to the correct place.

My issue:

I have a Linux server set up as a domain controller using samba with an LDAP
backend.  I can set the "passwdMustChange" attribute.  With Windows NT
4 clients, this works fine - the user is prompted for the new password and the
password change is submitted to the server. (The server changes the password and
resets the attribute so the user is not prompted again.)  This works perfect. 
When using Windows 2000, however, this does not seem to work.  It hangs for a
bit and then responds with a message indicating that the domain is unavailable.

Any suggestions?

thanks,

Chris
