NAS Issue
 

Hi

I have a basic Addonics NAS plugged into my router connected to a 250G drive. I can access the NAS homepage no problem but when I try to map as a network drive I get a pop up saying "Window Cannot Access \\same address as before".

The error is #0x80004005. Googling offers plenty of hits but no help.

I often get the same problem trying to access my Logitech Touch storage.

I am running W7 Ultimate.

Any help appreciated.

Re: NAS Issue
 

Can you access the files / volumes through the web management UI?

Re: NAS Issue
 

No. I can only see that the drive is there.

Re: NAS Issue
 

What is the address?

And what happens when you type "net use \\address" into a command prompt?

Re: NAS Issue
 

Do you have network discovery enabled in Network & Sharing centre?

Have you tried connecting with a numeric IP?

Re: NAS Issue
 

I have tried to access it with an IP I use to see the homepage to no avail.

Re: NAS Issue
 

Have you changed the web UI port per chance? ie - 192.168.1.5:8081?

Re: NAS Issue
 

Nope. I can still see the UI on port 80 without problem. I have downloaded nmap to probe for open ports and cannot see the drive contents on any open port.

Re: NAS Issue
 

Presumably the NAS unit is on a fixed IP. (?)

It might be worth hooking it up directly to the pc and setting the pc to a fixed IP in the same group, just to rule the router out of the equation.

Re: NAS Issue
 

Everthing on my network is fixed IP. I think this maybe a Win 7 problem.

Re: NAS Issue
 

It sounds like a possible firewall issue. I'd still like to know what happens if you try a direct connection with firewall disabled.

-- Always start diagnostics with the minimum kit involved.

Re: NAS Issue
 

I have tried it with the Win 7 firewall completely disabled but to no avail.

I works fine with XP with its firewall enabled. So it does appear to be Win 7 related.

Workgroup names are identical.

TIA

Re: NAS Issue
 

I had a similar problem with a basic NAS drive and win 7. The problem I found was just accessing the root folder. Maybe worth a try goto \\nas\[folder name] instead of \\nas.

Re: NAS Issue
 

Maybe you should start by saying what format the address is and the results of the basic connectivity test mentioned above. Twice.

Re: NAS Issue
 

I can connect to the web interface using http://192.168.1.250 without a problem in Firefox/IE.

Using the UI I can add various user accounts under the samba server settings. I can see these directories if I unplug the HDD and look at it as a USB drive. I can also see the drives under XP.

When I try and connect using Win 7 explorer as \\192.168.1.250\any of the accounts..

I get the same error that Windows cannot access \\192.168.1.250\any of the accounts.

TIA

Re: NAS Issue
 

What about if you go straight to a subfolder instead of the root like I said in my previous post?
e.g. \\192.168.1.250\mp3\
Assuming there is an mp3 folder on the drive. If the drive is empty use one of the windows XP machines to create a folder and try to access it in the way I described above.

Re: NAS Issue
 

I'm thinking this sounds similar to problems I've run into when networking 2 pcs together.

If you can create a passworded user account on the NAS via the samba server then next try creating an identical user account on the Win7 pc.

You don't have to log on with that account, it just has to exist. Once that's done, reboot and try connecting again.

That's fixed Win7 -> XP issues for me in the past.

Re: NAS Issue
 

Please try opening a command prompt, then type:

net use \\192.168.1.250

If there is a username/password required, you'll need to do:

net use \\192.168.1.250 /user:<name-of-NAS>\<username here>

and enter password when prompted. May also be worthwhile checking Windows' user account settings in case it saved a wrong password somewhere and keeps trying to use it. Before you do either of these, just do "net use" on it's own, and press enter, and take note of the output.

You could also try \\localhost to see if the SMB client in Windows is b0rked, if so that's a different issue.

Finally, also worth trying telnet/putty to connect to port 445 on the NAS to see if your computer can establish a connection at all.

Windows 7 has some more strict defaults for network protocol security, and if the settings don't match all sorts of funny things can happen.

P.S. A quick search suggests some people have fixed it by turning on network discovery. Do you have network discovery turned on? The settings you should use on Advanced sharing settings page are:

Network discovery - On
File and printer sharing - Either - should have no effect on this
Public folder sharing - Either - should have no effect on this
File sharing connections - Enable file sharing for devices that use 40- or 56-bit encryption
Pasword protected sharing - On
Homegroup connections - Use user accounts and passwords to connect to other computers.
