Error trying to Change paasword from a XP client

Hi All,

This is my Network Setup:

2 machines
Machine 1: Mandrake Linux 10.0, Samba 3.0.2a (that comes with the
Mandrake
10 community CDs)
Machine 2: WinXP Pro SP1

I have configured Machine 1 as the PDC, setup roaming profiles, shares
and users who log in from Machine 2. Everything works like a charm,
except for this 1 nagging issue. When I login as a user from the XP
Pro client (Machine 2), and try to change the password, I get an error
saying Domain cannot be found. The strange thing is, once I hit
cancel, it is able to autheticate and log into the same domain. Has
anybody run across this before ? How should I fix this ?


Thanks,
-Alexei
