We bought a new PC that is running Windows 10 64bit OS. When I copy file from Windows Server 2012R2 by share folder, the time is very slow and sometimes seem stop. I search from web which say it may be caused by the network card overload function. Thus, I tried to disabled and updated the network card driver but it still have the problem. Could anyone can help me ? The other PCs does not have this problem. If copy file from Windows Server 2008 to this PC also no problem. Thanks a lot. Paul
