Windows 7 64 bit and NAS

[cicatrix]

I have a NAS (Western Digital MyBook World Edition) and recently I've upgraded my OS to Windows 7 64 bit (from 32-bit Vista) and I'm experiencing strange problems with NAS presently.
When I start it up while Windows is working the system discovers it and allows access, but when I shut the computer down or merely switch it to sleep mode, after resuming I cannot see my network disk and I cannot access it (though it pings perfectly). It can only be cured by restarting the NAS.
On 32-bit systems everything works as clock. Is there something with 64bit OSs which may cause that?
I contacted WD support but they're pointing fingers at Microsoft saying 'it's not our problem'.

Hello Cicatrix,

I have an NAS storage drive, although not the same as yours. Having been through the same hoops as you I decided to investigate your product.

I fixed all of my issues by adding my NAS into the workgroup. By downloading the manual from http://www.wdc.com/wdproducts/librar...779-705013.pdf and going to page 125 out of 198 the manual clearly shows how to achieve this. Just remember that the Workgroup name you type in must be the same as the Workgroup you wish to share.

Please give this a go and post back with any success.

Kind regards

Steve

I have not yet managed to resolve this. By inspecting the NAS logs I saw that my machine refuses connection to the NAS or whatever 'Connection reset by peer' error means.
Something is definitely wrong with NetBIOS as it appears, but I haven't got a slightest idea what exactly.
The workgroup name is the first thing I checked, besides, the problem appears only after the computer is rebooted, when you turn on NAS when the system is operating everything works.
I'm even considering to abandon the whole x64 business and install the 32 bit version.

While I don't have a NAS I had a Western Digital hard drive and it sounds like the best action for your problem is to refer to the product manual. I was going to say that if it was a faulty product contact your Western Digit supplier (contact WD to find who your WD service/supplier is) and send it back. That is what WD support told me to do with my WD hard drive.

The 64 vs 32 bit is probably not the problem.
Though Vista vs Windows 7 might be.
You might just have found a bug in Windows 7 networking or WD compatibility.
Can you update the firmware for the NAS?

I don't think that the NAS is faulty since it's been working for quite some time and it still works with other machines. I'll try to upgrade the firmware but I don't think it will help. I'm going to set up more detailed logging on both the NAS and the computer though. The most frustrating thing about Windows is that it buries necessary information somewhere deep inside and it's very difficult to find exactly what's wrong if you're not an expert in windows networking.

If I put the question in more general terms:
What may be the cause if you can ping the machine but you don't see it and its shares in the network explorer and you cannot connect to them?

I have a D-LINK NAS that works from two Windows 7 64 bit machines.
