samba - Mar 2013 - Unable to connect from Windows 7 on samba server 3.4.7 running on ubuntu 10.04

Hi,

I cannot connect from W7 on my server Samba 3.4.7 on ubuntu 10.04.

I have tested the share on an other Linux machine, it is working fine.
The command to test is :
   smbclient  -U me //ipserver/me,

On windows 7
I am logged as "me", with the samba password
When I create a network drive (Z: connected to //ipserver/me), it says 
that it
cannot connect. Acces denied, but the icon become green (not red crossed).

But, surprisingly,  in a console (cmd.exe), I can access to the content 
of Z: , read, write, creating directory, ...


I have made many changes in smb.conf without any result.
Tested in an other windows 7 : same error.

The directory has access only for the user.
If I give access to the group, I can acces tot it by the network drive .


Any idea ? Of course I cannot update Samba to 3.6, because it needs to 
upgrade all the system, and I cannot stop the server for several hours.

Thank you,

Francis
