samba - Sep 2002 - Samba 2.2.3 & XP user profiles

Hi all,

I've got Samba 2.2.3 set up to share user profiles for some XP systems.
No matter what I try (setting Samba up as a PDC or just using shares,
etc etc) the user profiles are cached on the XP system until the user
logs off.

Is there any way of changing this behaviour? This appears to be a
built-in Windows thing, unfortunately I don't have a heck of a lot of
Windows experience so I'm not sure where to turn...

The problem is that my XP users rarely if ever log off...

Thanks!

Cheers,

Ross
