I need to access resources samba (samba-3.0.24-2.28) for SLES 10 SP1 from my windows 7.
The samba server is defined as a workgroup, which makes windows 7 have problems with it .. (I think that)
The behavior of windows 7 is: Displays the shares, you can access them, but no files appear, and if I want to create a file does not allow indicating no recourse.

Got it working with the 'protocol = LANMAN2' in smb.conf, but this does not work with GNU / Linux (changing the parameters of linux is no option for now)
With options 'min protocol' and 'max protocol' I have not had success, seem not to work.
I've gone round and round, changing the Windows registry, but could not make it work without changing the smb, conf (at least not to stop the access linux).
Right now I'm a little confused, I have not clear if I can make samba use 'protocol = LANMAN2' and I was using before (to work with linux)
Shared resources should allow access without entering username and password.

No way to configure samba 3.0 to work with Windows 7 without using 'protocol = LANMAN2'?
or make samba use various authentication protocols?

Thanks for reading this far .. (sorry for using translate)
Below I leave my smb.conf

        workgroup = SISTEMAS
        server string = Servidor de aplitest
        map to guest = Bad User
        printcap name = cups
        add machine script = /usr/sbin/useradd  -c Machine -d /var/lib/nobody -s /bin/false %m$
        logon path = \\%L\profiles\.msprofile
        logon drive = P:
        logon home = \\%L\%U\.9xprofile
        preferred master = No
        local master = No
        domain master = No
        usershare allow guests = Yes
        cups options = raw
        include = /etc/samba/dhcp.conf
        ;Debug logging information
        log level = 5
        log file = /var/log/samba/samba.log.%m

        path = /path/shares/boss
        force user = user1
        force group = user2
        read only = No
        inherit acls = Yes
        guest ok = Yes

if I add these lines runs windows 7,
   #min protocol = CORE
   #max protocol = LANMAN2
   protocol = LANMAN2   
   client lanman auth = yes
   client ntlmv2 auth = yes
   lanman auth = yes
   ntlm auth = yes
