[Samba] sometimes, roaming profile is not found

[sylvain.david at etranges-libellules.fr]

Hi,

I use samba 3.0.22 on Debian Sarge as PDC for windows XP SP1 and SP2. 
Sometimes, users get the message "Windows cannot found the roaming 
profile on server so user will get a default profile". (sorry, it's not 
the official message,  I had to translate, because I get the message in 
french) This error comes only if user log in quickly after the boot. If 
they wait a little (15/30 seconds) they didn't get the message.
When they get this error, I tell them just to close their session, and 
re open it. And it works fin, they didn't get any error message.

At first I think it was an ACLs problem, but .... it works if user wait 
a few seconds before login.
So I think this problem deals with something about a netbios refresh or 
windows is not fully ready when it display the login screen. Is there a 
workaround for this problem, like delaying the login screen with a nice 
registry key, or perhaps it cames from my samba configuration ?

Thank you.

Here's my smb.conf :
