[Samba] roaming Profiles

[Didier.roques at brive.unilim.fr]

Hi all

I've updated a server from samba 2.2.8 to 3.0.20 .
and i've got some problems with roaming  profiles on Win2k clients 
workstations .
On WinXp clients everything works fine but on win2k clients the client 
says that it cannot load roaming profiles.
I've disconnected and re-joined the machine to the domain , and if fails 
again:

 logon path = \\%L\Profiles\%u

[Profiles]
    path = /%G/profiles
    browseable = no
    writable = yes
    root preexec = PROFILE='/%G/profiles/%u'; if [ ! -e $PROFILE ]; \
                then mkdir -pm777 $PROFILE; chown '%u':'%g' $PROFILE;fi

An idea ?
thanks in adavance
