Hello,
I am using DSM 6.17. When using a Mac to transfer files, using de afp network protocol, no errors found. But when using windows 10 (have tested with 2 PC) and also windows 7 (1 pc tested) , using Samba network protocol, after copying some MB, the copy stops with the Error 0x8007003B. I have tried to change the MTU manually to the same of my Windows, changed SMB to SMB2 in minimum/maximum protocols, with no success. Firewall down, Antivirus down, same error. I have googled a lot to find the solution. Any ideas? Thanks...
