keep dropping network path error 0x80070035

HEy guys

So i just added a new server to my home network,and i get insane good speed, however, i keep losing the connection with error 0x80070035 network path not found even though i was just working there.

I have to reboot the pc´s to make it work again. Sometimes if i wait,connection comes back a few mintues later,but this is really annoying as it happens for example when i am copying m2ts files of 30GB and have to start over due to network path dropped.

No machine runs windows firewall,they have been turned off in services completely.
I run this through a linksys E2000 and i have Eset NOD32 Internet Security running on 2 of the 3 machines. I have tried disabling Eset but that didnt stop the dropout.

Any ideas?

It was Eset that was the cause.
