Unable to map a network drive using Windows 7?!

Hello:

 

I'm having a problem connecting Window 7 to a NAS.  It used to work... with other OSes (XP and W2K).  But it will NOT with Windows 7.

 

At any rate, when I either try to map a network drive from Explorer, or just enter the UNC in the Address Bar in Explorer, I get a very generic “Windows cannot access” error with a code of “0x80004005 unspecified error”.

 

So after searching on that error across the web, here are some steps I have taken:

 

- Turned the firewall off

 

- Ensured MS Client for Networks is installed on my NIC

 

-  Verified File and Printer Sharing is enabled

 

- Made sure the Server, TCPI/IP NetBIOS Helper, and Workstation services were running

 

- Enabled NetBIOS over TCP/IP

 

- Changed the Lanman authentication to the most unsecure option

 

None of that helped. 

 

I have Cygwin installed on the box though.  So I ran smbclient -L \\server\share and it give me the finger due to SMB signing required on the server side.  Hmmm... I'm on to something here.

 

After some poking around I turn signing off with this:  smbclient -L -S off \\server\share

 

and it works!!!  I can see all the directories and files on the NAS.

 

In turn, I go back to Windows and remove mrxsmb20 from lanmanworkstation's dependencies, set mrxsmb20 to disabled, and reboot the workstation.  Yet, when it comes back up, I still experience the same problem. 

 

Since I was able to navigate the NAS with the smbclient, I know my network and integration is set up correctly.  Mapping a drive in Windows is still problematic though.  So I go back to my original question:  what does it takes for Windows to map a drive?  Meaning what are the settings, services, etc., which are dependent upon the mapping procedure?
