Unable to access Readynas NV+ shares using Windows 7

Since this toppic seems to describe my Problem perfectly I will add my part hereafter.

I also have a problem accessing samba shares on my nv+ from a windows 7 (64bit) professional notebook. (Lenovo Thinkpad)

The Client for Microsoft Networks was in place allready on my "Intel(R) Centrino(R) Ultimate-N 6300 AGN" Wifi adapter.

I can connect to my nas via http (browser) and access the admin interface. I also see the media server in my network view, but the samba share is not visible as it is from my other pcs which are mostly win-xp based, but also include one vista pc.

I have tried several possible sollutions to this problem allready, and have lost track of all possible configurations...

If I remember Correctly i have changed 2 options in the Lokal Windows Security Guidelines concerning

Network security: LAN Manager authentication level
Send LM & NTLM responses

and

Minimum session security for NTLM SSP
Disable Require 128-bit encryption

This didn't help.

I have also tried changing several configurations on my home network and on a share on my readynas.
Since I do not really know what parameters are helpful for solving my problem, I would rather ask for help here now...

For the time being I have switched the Readynas Security mode to "User" and named the workgroup to be the same as the name of my homenetwork.
My other PCs don't seem to have problems with this configuration.

Also the username of the windows user is identical to a user set up in the nas with a personal share and permissions for 3 other shares.

Please ask me for any configuration parameters, which could be responsible for my problem, since I cannot identify what
information would be important.

I am adding some info here which might be of use:

C:\>nbtstat -a nas
Drahtlosnetzwerkverbindung: (Wireless connection)
Knoten-IP-Adresse: [foo.bar.foo.bar] Bereichskennung: []
      NetBIOS-Namentabelle des Remotecomputers
       Name               Typ          Status
    ---------------------------------------------
    NAS            <00>  EINDEUTIG(unique)   Registriert(registered)
    NAS            <03>  EINDEUTIG   Registriert
    NAS            <20>  EINDEUTIG   Registriert
    ..__MSBROWSE__.<01>  GRUPPE(group)      Registriert
    WORKGROUP     <1D>  EINDEUTIG   Registriert
    WORKGROUP     <1E>  GRUPPE      Registriert
    WORKGROUP     <00>  GRUPPE      Registriert
    MAC Adresse = 00-00-00-00-00-00

I have now also tried to connect to the nas as a network drive using IP-Adress instead of the Hostname.
Another Failed attempt.

Another Sollution stated, that disabling ipv6 could solve a simmilar problem. Disabling ipv6 on my wifi adapter did not help.

I have now tried switching from home-network to workplace-network setting,
thereby leaving the Home-Network.
For testing reasons my Share settings are atm:
- Network recognition on
- File and Printsharing on
- Fileshareconnections with low encryption
- Password protected sharing off
- Homenetwork connections: use Useraccounts and Passwords for connections

Using the global network topology view the nas is shown correctly integrated into the network, but I still cannot access the shares other than with http.
