samba upgrade problem

["Benedict Verheyen" <linux4bene@pandora.be>]

Hi,

since i upgraded from 2.x Samba to 3.x i get errors (sent by
logcheck). It's when i connect from an XP machine.
I can copy or read files from my shares on the linux machine and
i can log in without any problems (Server is configured as PDC).
So everything works but i don't understand why i get these errors then.

Anybody have an idea of what could be wrong?
