Network file copy error x86/x64

[Guest Campbell]

We currently run a network of 30+ XP Pro PCs. We have a added a few XP x64

machines and, whilst they can get on the network ok (are visible, can browse

and be browsed by others), they give an error when trying to copy files from

other computers (both 32-bit and 64-bit). This is the error message:

 

"Cannot copy [filename]: The specified network name is no longer available."

 

However, they work fine if you push the file from another computer (x86 or

x64) to the x64 machine.

 

Anybody have any ideas? We move around a lot of data and it is really

starting to cause us some issues...

First, and foremost - you really need a server based network. The

limitations on connectivity for XP machines means that you're going to

continue to run into problems. It sounds like your network is a good fit for

Small Business Server.

 

There are known issues with some settings on GigE network cards that might

be affecting you, but I would have expected problems on both 64 bit and 32

bit Windows. Though the latest service pack on Windows XP x64 _does_ enable

the settings that can cause problems.

To disable checksum offloading:

 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

Click Edit, point to New, and then click DWORD Value.

Type DisableTaskOffload as the entry name, and then press ENTER.

Right-click DisableTaskOffload, and then click Modify.

In the Value data box, type a value of 1 , and then click OK.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

On the Edit menu, point to New, click DWORD Value, and then type EnableRSS .

Double-click EnableRSS, type 0 , and then click OK.

Re: Network file copy error x86/x64

 

Thanks for the suggestions. We are, in fact, already running Server 2003 for

limited file server purposes. We are a small media company that uses

high-end PCs for multimedia creation so our current (decentralised) setup

makes the most sense for the moment. As for the RSS, I had already tried

disabling that but to no avail. It is definitely a new problem to us (we

have not had it with the 32 bit machines). I am not 100% sure that XP x64 is

to blame either, as the 4 machines are all running the same hardware and it

could possibly be a hardware (or driver)-related issue. Unfortunately, I

don't currently have access to a different PC running x64 to be able to

provide a fair test. At this moment, however, it would seem to point towards

an OS issue. I will try the TaskOffload suggestion and report back!

Re: Network file copy error x86/x64

 

Right, I've tried the registry changes but they've had no discernible effect.

Here's the current situation:

- x64 PCs can access files shared on x86 PCs.

- x86 PCs cannot access files on x64 PCs - they receive the following error:

"Cannot copy [filename]: The specified network name is no longer available."

- x64 PCs cannot access files on other x64 PCs - they receive one of the two

following errors:

"Cannot copy [filename]: The specified network name is no longer available."

OR (occasionally and, seemingly, unpredictably)

"Cannot copy [filename]: Cannot read from the source file or disk."

 

Also, when I try to copy a file from any PC using x64, I get an Internet

Explorer window asking "Do you want to move or copy files from this zone?".

Is this a new security step that has been added in x64 or could this have

anything to do with it?

Re: Network file copy error x86/x64

 

I'd look into the drivers for those NICs as a start. Since it only happens

on the 64 bit machines, and it happens between 64 bit machines and they're

the only ones with that hardware...

 

I routinely copy very large files between machines. To and From 64 bit

machines, and to and from 32-bit machines on my network. I did this for 2

years on XP x64, Windows Server 2003 x64, and various 32-bit machines. I no

longer run XP x64 in my daily work - those two machines have moved to Vista

64. But I never experienced this. Nor do others here. So I seriously doubt

it's the OS.
