Data transfer between OSX 10.9 and WIN 7 stops

Hello,

Unfortunately, I have a problem with the data sharing through SMB.

I can connect easily to my Mac and see shared folders or data. But in attempting to copy files from Mac to Win 7 PC there is an error. The data transfer is terminated after a while. The file used in the test is an MKV with the size of 1.34 GB.

The Mac is accessed from a Win 7 PC with administrator privileges. The systems are connected via Wi-Fi 802.11 n.

The exchange of data between OSX in use of SMB or AFP works without any problems.

Maybe someone has a solution or a tip for me.

regards
