Scheduled Robocopy task fails with 0x10 error

  • 772

I'm trying to schedule a file-sync between two dedicated servers on a LAN. The remote machine is running Windows Server 2003 and the local machine is running Windows Server 2008.

I mounted the remote folder as the J: network drive to overcome any permission issues and when I run the command manually everything works as expected and the folder contents are mirrored:

robocopy J:\\ C:\\Files /MIR > c:\\robocopy.log

But as soon as I put it in a scheduled task, it fails with return code 0x10 (16), which is a serious error. So I assumed a network permissions error and tried scheduling the action between two local folders. The same error occurred and no robocopy.log output file is created. I am running the action as an Administrator.

Why is my scheduled task failing?

Output from schtasks /query /v /fo LIST /s localhost for reference:

  1. Instead of using a mapped drive letter, use the UNC path of the share (\\servername\sharename\folder). That'll simplify things since your mapped drives are associated with your session, not necessarily the session that the scheduled task runs in.

    Next, ensure that the user associated with the scheduled task has access to that share.

    That should get you fixed up.

    Solved by adding the following action before calling the robocopy command:

    net use j: \\RemoteHost\Files RemotePassword /user:RemoteUser

  3. I recently encountered this problem and solved it by inserting a tick in the scheduled task labelled "Run with highest privileges".
