Hello Edgar,

thanks for your answer, attached there are 2 captures of a current Windows 10 client (explorer.exe) copying a file test.txt with a ~400kb ADS "mystream" in it onto a 2012R2 server.

In this capture the share is a ReFS (128k sized ADS supported) volume, see packet 487 ff.

In this capture the share is a vfat volume with no ADS support, see packet 147 ff.

There are also the screenshots of the dialogues the Windows 10 client shows when the ADS writes fails for both cases.

Thank you!
