[Samba] problem with roaming profiles

[Morganne witheredrose]

Version 3.0.26a
2.6.22-gentoo-r9

configuration: http://pastebin.com/m3b84d11e

The problem is the following:
I login with a network account in a windows xp box for the first time.
Everything is ok, profile loads completely.

If i try to login with this account in another pc, then the account is
being logged ok, but the profile is not loaded completely. You cant
even run firefox that is in desktop.
The network drive is mounted and you can access the files.

I cant figure out what i am doing wrong here ...
Could you please help me on this ?
