It's clear to me, that I do have a password in order to change it. 
I read about the problem that an old password has to be "older" than 
three times of usage on a NT-station. But I have a Linux-station.
I tried more than 10 different old passwords.
Doesn't help at all.

And I know that the clients authenticate themselfes on the server 
(also password server for other clients). The users are authenticated 
using security = user.
And I can change the passwords as a user, when I'm telneting to the 
server saying smbpasswd.

So I don't understand why the password changing utility of Win95 
can't find any password at all, while the client uses it all the 

Do you have any further suggestions ?

Thanks a lot for your responding,
