Windows 7 error accessing shares
« on: February 05, 2010, 03:35:03 AM »

I have upgraded my laptop to Windows 7 Enterprise 64 bit and now have problems accessing shares on my DNS-323 - Firmware 1.07 (I also tried 1.08).

I am able to map a drive (both manually as via Explorer), but when I try to access the mapped drive I get an error "An unexpected network error occurred". See below an example from the commandline

This happens in all situations:
- When a username and password are required for the share. It does not matter whether the username and password are the same as a user on the laptop or a different one
- When access to the share is open for "ALL"

From another laptop with Windows XP PRO I still have access like I used to.

 C:\>net use z: \\192.168.100.102\Docs /user:xxxxx
  The command completed successfully.

  C:\>z:
  An unexpected network error occurred.


Please Help!

How are you connecting to the NAS unit (wired and/or via wireless)? Also, did you use the NAS unit's IP Address to map to the drives or did you use the Server Name (\\DNS-323\...)?

I have experienced a difference when attempting to connect to my NAS depending if I am using a wired versus a wireless connection when using XP however Win7 connects with no issues regardless of the connection type.

I have just upgraded to Win7 and I can access the NAS system using both connection types where XP had issues connecting to the NAS system via wireless where connecting via wired worked every time.

The problem always occurs: wireless and over cable, using ip address, hostname and fully qualified hostname.

Works just fine here, I'd check for firewall issues.  I tried it with a wired connection, then shifted to the wireless connection.  I'm running Windows 7 Ultimate.

Are you running password protected shares on the NAS?  Can you access them normally through the Network browse window?

The problem occurs with both password protected shares as well as with shares open for 'ALL'.

In the network browse window I see a connected drive:

The icon shows a drive with a green connection to the network (so not a red cross):

(Z:) MP3 (\\Diane)

When I double click the icon to browse the drive I get the error message "An unexpected network error occurred".

I was asking if you don't have the drive mapping, can you simply browse to the drive and access the shared files?  In other words, do you have any access to the NAS from Windows 7?

You mean can I go there in the browser by entering \\Diane\MP3 in the browserbar? 

No, after being prompted for my credetials I get the following error message:

\\Diane\MP3 is not accessible. You might not have permission to use this network resource. Contact tehe system administrator of this server to find out if you have access permissions.

An unexpected network error occurred


And the second time I try the last part reads:

The system detected a possible attempt to compromise security. Please ensure that you can contact the server that authenticated you

That's pretty odd.

One possible issue that I just noticed.  You can't have password protected shared and anonymous shares on the same box with the current firmware for the DNS-323. 

Try mapping to a password protected share and enter the name/password and have it saved.

I have tried and then also removed password protection from all shares on the box, but still no success :(

Does the Win7 box connect with other computers shares?

Only when I am at the office. Then I am also logged onto work domain. At home these shares are not connected and visible as not connected drives.

You're saying you can't connect to shared resources in your home network at all?  Have you tried disabling all firewalls on that machine?

I meant to say that I cannot access my office resources, but I can in the office.

I tried connecting at home to my NAS with the Windows firewall switched off with the same result. Unfortunately I have no other shareable resources on my home network I can try now.

BTW, Really appreciating that you are helping me - thanks!
