The specified network name is no longer available

Hi folks,

I have a workgroup with two Win XP Pro SP2 PCs.

It's rare that we copy files between them, but today I tried copying some
MP3s and got this error message after a few seconds of trying to copy: the
specified network name is no longer available. It happens if I try and push
the files onto a share from the source PC, or try and pull them from the
destination PC.

I've Googled the error, which others have encountered in a similar
situation, and tried some suggestions i.e. stopping the Wireless Zero
service and disabling 802.11 authentication. No errors are showing in Event
Viewer, although the application log was showing information events about
the EOPPol service (hence I disabled this based on another Google
suggestion, although it still hasn't helped).

The source PC is using an nForce integrated chipset. The destination PC is
using a Realtek 8130 PCI NIC. They're wired using a Linksys WRT54G router.
There used to be a wireless card in the destination PC, but after continual
dropping of the connection we swapped it for the wired Realtek NIC.

I've had to resort to burning the MP3s to CDRW to transfer them, but this
seems ludicrous when we have all this network hardware here. Otherwise the
network is fine, and we access the Internet without issue.

Any ideas?

Thanks

Hi Stainless,

Questions:

1. - Did you check the Workgroup Name on each computer, to make sure the
Workgroup Names are the same?
2.- Make sure each computer name is different?
3.- Make sure that File and Print Sharing is enabled on both computers?
4.- Did you make sure that you allowed Full access thru the Firewall on both
computers to each other?
5.- Have you enabled File Sharing on the files within certain folders?

Hi Stainless,

Hi, thanks for the reply.

1. - Did you check the Workgroup Name on each computer, to make sure
the Workgroup Names are the same?

Yes, they're both the default "workgroup".

2.- Make sure each computer name is different?

Yep, definitely both different.

3.- Make sure that File and Print Sharing is enabled on both
computers?

Yep, both enabled.

4.- Did you make sure that you allowed Full access thru the Firewall
on both computers to each other?

I just double checked, and unbelievably the firewall was switched on for my
PC (I recently reinstalled Windows, so I guess this is why). Although I
would have expected this to block access full stop, rather than blocking
larger file transfers. Unfortunately even when I disabled it, I still have
the same problem and error.

5.- Have you enabled File Sharing on the files within certain folders?

Yes, file sharing is enabled with read persmissions for "Everyone".

As an aside XP's workgroup permissions are very strange. At times within XP
workgroups I can share a folder with Everyone access and there's no issue,
everyone can access the folder. Then at some point this stops happening and
I need to have an account open with the same name and password on both PCs
to allow access (aside from the file copying issue). I don't know what
causes this, but I would love to understand the detail of why. It makes
simple workgroups far too complicated, and it's a real shame Microsoft added
this, aside from the random behaviour.

Just to add, I did some more testing, and the behaviour is strange. I was
able to copy ten 1kb files without any issue. Then I was able to copy three
or four 5Mb MP3 files without issue. I tried ten, and got the error. Then I
tried three again, and got the error. I then got the error with even one MP3
file. But it would still let me copy the ten 1kb files.

When I Googled the issue I notice it came up for people who were copying
large files, of several hundred Mb.

Hi Stainless,

I had the problem you are mentioning. I use Iomega Quik Sync 3. I have
Windows XP Home Edition on a Wired Computer sync'ing My Documents folder
over to my Faster Wireless Computer thru my D-Link Router for Backup and
Availability to both computers. I had to call D-Link and they told be, since
I had Comcast to change the MPU default value of 1500 to 1492, because it
was crashing the Router and could not get out on the Web, until I rebooted
the Router.

Could you be facing a similar problem?

I was accessing the WEB on my new Computer, while files were being
copied to another drive and partition on my new Computer.

Call Linksys, and tell them what is happening and see what they say.
Report back, please.

You might have your network adapter's power management properties enabled.
Go to its entry in Device Manager, double-click to get its properties, and
on the Power Management tab uncheck the box that says "allow Windows to
turn off this device while in use".

As for networking, since you didn't tell us what versions of Windows you are
running and the Service Pack levels, it's hard to be specific. Here are
general networking troubleshooting steps. This is boilerplate, so you may
have already done some of the steps. Workgroups are not particularly
"complicated" and Windows machines do not need to be in the same Workgroup
to share files and printers; Workgroups are simply a cosmetic and
organizational device.

This is most commonly caused by a misconfigured firewall. Run the Network
Setup Wizard on both computers, making sure to enable File & Printer
Sharing, and reboot. The only "gotcha" is that this will turn on the XPSP2
Windows Firewall. If you aren't running a third-party firewall or have an
antivirus with "Internet Worm Protection" (like Norton 2005/06) which acts
as a firewall, then you're fine. If you have third-party firewall software,
configure it to allow the Local Area Network traffic as trusted. I usually
do this with my firewalls with an IP range. Ex. would be
192.168.1.0-192.168.1.254. Obviously you would substitute your correct
subnet.

If one or more of the computers is XP Pro:

a. If you need Pro's ability to set fine-grained permissions, turn off
Simple File Sharing (Folder OptionsView tab) and create identical user
accounts/passwords on all computers.

b. If you don't care about using Pro's advanced features, leave the Simple
File Sharing enabled.

Simple File Sharing means that Guest (network) is enabled. This means that
anyone without a user account on the target system can use its resources.
This is a security hole but only you can decide if it matters in your
situation.

Then create shares as desired. XP Home does not permit sharing of users'
home directories (My Documents) or Program Files, but you can share folders
inside those directories. A better choice is to simply use the Shared
Documents folder.

If that doesn't work for you, here is an excellent network troubleshooter by
MVP Hans-Georg Michna. Take the time to go through it and it will usually
pinpoint the problem area(s) - http://winhlp.com/wxnet.htm

I've just spotted that I can push PCs onto the source PC without issue, it's
only the other way around when files are being transferred to the
destination PC (either pushed or pulled) that the error occurs. Does that
suggest the problem lies with the destination PC?...

Hi Stainless,

What do you mean by pushed? What brand of Firewall and version are you
using? Does it have an Incoming Log?

Whoops, there was a typo there. It shoudl read push MP3s onto the source PC.
Push as in copy using the destination PC, rather than pulling from the
source PC, is that makes sense (just to imply which PC is actually being
used).

There's no firewall (I've checked and the Windows firewall is definitely
turned off now on both PCs), except on the router itself.

The thing is I can copy very small files e.g. 1kb, but large files e.g.
2-3+Mb, cause the error :-(

With that last information, look to your hardware. NIC's, cables, router in
that order.

Just to update on this, I realised that hte directory that the MP3s were
comng from has around 870 folders in it. I wonderd if this might be the
issue, so tried copying XP's SP2 from one PC to the other... and it worked
without issue (270Mb). I tried another folder with some MP3s in, which had
around 60 subfolders. It worked at first, then started to have the same
"network name" error again.

It's a really strange problem...

Hi Stainless,

Call your Router's Support number and tell them what is happening and
asked them how to fix it.

I had a similar problem. Mine / D-Link told me to change the default MPU
from 1500 to 1492. The setting is located on the WAN Page in the Router. I
have Comcast Cable.

I've got a Linksys WRT54G. What's really strange though is it only seems to
affect one PC, although I need to double check with another laptop we have
here at the moment.

I think this is a setting in the router that's easy to access. I'll double
check. Thanks for the reply!

Did you ever figure this out? I have the same problem. See post below:

I recently reformatted a Dell laptop (D600). I downloaded all the drivers
from Dell including the wireless one. I have a Intel (R) Pro/Wireless 2100
LAN miniPCI Adapter. I can connect to the company's network fine and the
internet as well.

My problem starts when I try to copy a file from the server to the laptop
that is bigger than 2 MB. When I copy and paste on the laptop, the wireless
disconnects momentarily and then I get an error "Invalid File Handle" or
"specified network name is no longer available." Basically, it just can't
stay connected long enough to copy it.

I am having no other connection issue. If I try to copy a file less than 2
MB it is fine, no problems. I can stay connected to the internet/network all
day long, no issues either. Any ideas? Where would there be a size setting
for what I can copy?

Have you check this troubleshooting?
