samba - Nov 2003 - password change from win95 client doesn't work

Hi All,

I've got a Samba client that runs Windows 95 (way old, i know). Logging 
onto the domain rocks! However, changing the domain password using the 
control panel results in an error (translated from dutch): "Access to 
the network has been denied"

What is wrong?
