Copying large files from windows to NV+

[cnecne]

Hi folks,
when i copy large files (>500MB) to the NAS, I get the following error message:

Fehler beim Kopieren der Datei oder des Ordners
xxx kann nicht kopiert werden: Der Netzwerkname ist nicht mehr verfügbar!

I have installed the latest firmware on the nas, my pc has a gigabyte GA-P35-DS4 motherboard with latest network drivers.
I have a 1GBit Net, the conection is fixed to full duplex.
On the nas, i ave installed the "master browser priority"-addon.

So what can i do to copy all files?

Any ideas?

[super-poussin]

the addon is : ToggleMasterBrowser Right ?

is it better without the addon ?

what does nbtstat -c output ?

what does nbtstat -a @ip nas output ?

what does nbtstat -a @IP PC output ?

Right, that's the addon.

I can't say that the connection breaks are less than without.

I have called nbtstat with all your given parameters, but under all circumstances, all machines are available, even immediately after a broken connection!

Waitnig for ideas,

I found a solution for my problem myself:
Unchecking the oplocks setting in the share did it!

Now I can copy huge amount of data (>100G) to the NAS without any errors!
