Upgraded a Windows 7 computer acting as a server to Windows Server 2016 Essentials. Made it a Domain Controller.
Copying large (>100gig) files FROM the server to other machines works fine at around 50mb/s
Copying large files TO the server goes at around the same speed for 1 to 2 minutes, and then I get the error
"There is a problem accessing \servername\F
Make sure you are connected to the network and try again."
This can be replicated on 3 different windows 7 machines. Prior to the win2016 upgrade, this was not an issue.
