[SOLVED] Robocopy access denied, despite having Full Control?

Robocopy access denied, despite having Full Control?

Pretty straightforward script:

ROBOCOPY \\servername\S$\SCCM2012\SCCMPackageSource\Files C:\Files /S /COPYALL /MIR /IS /LOG:C:\Copy.log

I can run this as administrator just fine, and all the files get copied correctly. However when I push this script to a computer as an Application via SCCM 2012 and run it, the log file gives me the following:

NOTE : NTFS Security may not be copied - Source may not be NTFS.
2016/07/27 10:05:31 ERROR 5 (0x00000005) Accessing Source Directory \\servername\S$\SCCM2012\SCCMPackageSource\Files\
Access is denied.

Both the SYSTEM account and the SCCM Network Access Account have Full Control over that folder. The folder is not shared. Tried with the /ZB switch as well, but that didn't make any difference. Any thoughts? Thanks!

Solution

Problem was resolved by Sharing the folder and giving Read access to the Everyone group.
