So I recently picked up a Dlink dns-321 NASD. I had gotten one for my parents a year ago and they liked it, so I needed more space (2tb mirrored) so I got one for myself.
I keep loosing connection or something with this thing. I'm guessing?? I have the some problem hard wired or wireless.
So sometimes it disappears from my network list. Sometimes I'll be in a folder and go back one level and get an error, sometimes when I go forward, sometimes when I try to open a file.
Any ideas?

Replace the network cable. Plug the network cable into a different port. Replace the hub/switch.
If those don't help, it's time to do the warranty thing.

Is this sarcasm? my detection may be off.
The router is only a month old, the nasd is new. I'm using the new network cable that came with it.

Are you running Win 7? It does some strange things with my Z drive sometimes. Win XP doesn't.

No, it's proper troubleshooting. You try to isolate the fault.
Replace one element at a time until it works.

I'm running XP, but I'm having the same problems with a 7 machine.
I don't think it a cable because 2 reasons. I can access the box using my browser and play with all the settings.
The box also has a P2P app that I'm using right now to download 36GB of stuff. ;/
I guess I could try the cable, but I don't have a spare router. My last spare died.

I had the same problem with Win7 and my Linux file SAMBA shares. It turned out to be a problem with Avast Antivirus. I dumped it and I haven't had a problem since.

Hmmm... I'm running panda on both machines. Let me try turning it off.
Not it.
It just let me go in 3 folders deep, then not open a file and not go backwards.

Could be a screwed up ACL.
If this is Vista or 7 go right click try as administrator, or get into the properties of the root folder, turn off inheritability of security permissions, then turn it back on, so it has to re-set security for all the sub-folders.
-
You appear to have it mapped as a name. Can you remap using an IP address or do you have that name configured in your hosts file? You can get the same error if Windows "forgets" the name to ip mapping.
The permissions statement is likely a red herring. Windows assumes everything is a permissions error at times.

What is and ACL?
When I try this from the 7 machine the security tab displays a message, no setting.
The requested security information is either unavailable or can't be displayed.

Do tell more. That went a bit over my head.
The name it is using was auto configured.

Here is a link for the emulator. Maybe that would help.

Go here: http://helpdeskgeek.com/windows-7/windows-7-hosts-file/
That'll get you started on editing the hosts file.
Next, open a cmd window (type cmd in Start-Run, then press enter). When in the cmd window, type "nslookup dlink-bf6935" without the quotes, press enter. Hopefully you'll get an ip address back (something like 192.168.1.1 but it could be different). Enter the following int your hosts file: dlink-bf6935 <the ip address you just got in the previous step>.
Hmmm, it just occurred to me that this device could be getting it's IP via dhcp, which means editing the hosts file is a lost cause.
Can you post a PDF of the manual? I need to get familiar with this thing's operation.

I'll give that a try tomorrow. I'm getting the evil eye right now from my other half. She wants me in the bed not on the puter.
I gave it a fixed IP when I set it up. 192.168.1.254 which is out of my DHCP scope.
Here is the link for the manual.
ftp://ftp.dlink.com/Multimedia/dns321/Manual/dns321_manual_100.pdf (http://ftp://ftp.dlink.com/Multimedia/dns321/Manual/dns321_manual_100.pdf)
But like I said its not just the 7 machine being a problem, its xp also.
Thanks also, computer help is always better from here than Pakistan.

Not sarcasm. You're loosing connection. There's a limited number of things to try.

Sorry, Access Control List. what Windows computers and servers/domains record all the file and user permissions in. Even if the NAS isn't a windows machine, it's probably using LDAP Lightweight Directory Access Protocol, which Windows security uses.
Can you right-click folders and set security permissions on them? Or can you only do it through the NAS's interface/webpage etc?
I'm just throwing this out there because you can drill in a few folders, then get access denied that sounds like busted permissions/security. If you can set security with the standard windows dialouge for that, going to the advanced options, then removing inheritability to child objects, then re-adding it is a quick and dirty way to force a set of permissions on an entire file heirarchy.
Otherwise, you are just losing connection, or it's doing something so dumb/slow it's giving up and timing out.

Windows is kind of stupid when it comes to this sort of thing. It says it's losing connection, but it's really losing the device logically.
Never Retreat: I read through the manual. This thing appears to run some sort of SMB Share (prolly Linux with Samba). I suspect you're having a workgroup/domain issue. I've run into similar problems with Linux/Samba myself. The error would be similar or identical to what you posted above.
Check your workgroup settings. If you hardcoded an IP, put that into your hosts file for good measure.
It supports FTP access. Use that as a test. FTP is not dependent on Microsoft's SMB networking, so it'll work even when "share level" access fails. If that fails too, then you likely have a connectivity issue, but if it works and your normal access method fails, you definitely have an SMB/workgroup/domain issue.
On page 24 of the manual, there is a section on setting up permissions. One of the tricky things about workgroup level networking and permissions is that authentication is managed by each host. Even though you *think* you are using the right account, there could be minor differences that make it not so. Make sure usernames and passwords are spelled correctly. Make sure the account on the NAS matches what you use to log into your computer (that info gets passed to the NAS when you access the share). Sure, you can use different accounts and provide those credentials when you access the share, but it adds another failure point.
Do as AJ says and make sure your permissions are populated from top to bottom and allow your user account full access. I don't think this is the problem since it affects your ability to access directories that you were in recently, but it wouldn't hurt.
Unfortunately, this thing doesn't appear to support WINS and that is a big help with Workgroup level networking. I know MS did away with it recently, but IIRC, it is still there in XP.

Ping will tell the tale.
Test by pinging by name, pinging by IP address, and trying to get to its internal web page by name and/or IP.

Not always. It'll tell you IP connectivity is available, but won't confirm SMB connectivity. Windows workgroup/domain networking is a bit decoupled from straight IP. It runs over IP, but can fail even when you have IP connectivity.

first try setting up your fixed IPs for your whole network. fixed a lot of intermittent crap on mine. :laugh:
you do this(if D-Link hasn't changed it. if it's not here let me know and i'll find where they put it. ;)) under setup | network settings | DHCP Reservations List.
here's a sterilized version of mine. :laugh:

next up turn on/off uPNP
check for a new firmware for your router/networked drive box.
oh and make sure you have your local network setup in your firewall. ;)

Ok I edited the host file.
How do you ftp to something thats on a local network?
I Removed all the different user groups and permissions I set up. So its wide open.
There are no properties for the folders viewable in windows.
Still nothing.
Its also using the newest firmware.
I have off tomorrow so I might call tech support. [barf]

If you have the IP address, then you can type in your browser address bar the following:
ftp://<never retreat's NAS IP address>

No dice, I configured the ftp settings to wide open.

FTP from a command prompt.

Sure but ping does a good job of telling you whether you need to oh, for example, Replace the network cable. Plug the network cable into a different port. Replace the hub/switch.

Pardon me for being to lazy to type out the steps for opening a command prompt. :D
