[Samba] Some PDC problem...

[pflist]

Hi, i recently decided to try samba as a PDC for my little home network (5 
PCs). So far everything is working fine, there's only a little problem with 
my roaming profile. Here how i see what's going on:

When the user logon for the first time on the machine (and on the domain), it 
creates a local profile. When the user logoff, it copy that profile on the 
PDC... so far everything is ok. But i found that when the user log in again, 
it won't use the profile on the PDC but the local one (even if it is 
specified as a roaming profile under System Properties / Users Profiles). I 
tried deleting the local profile, but it creates a new one and still won't 
use the one on the PDC... 

I've googled and found some hint (like synching workstation time with the 
PDC) but nothing that could do the trick.

If anyone can give me some more hint... thx a lot.

The PDC is Samba 2.2.8a on Slackware 9.0
Workstations are Win2k Pro SP3

here's my smb.conf:
