Has anyone used robocopy to copy permissions from the Isilon?  If I user the following command using the "U" I get the following errors

robocopy /E /COPY:DATSOU /DCOPY:T y:\ E:\Test-Mirror-RoboCopy /LOG:"C:\robocopy-TestRobocopy-2014-02-19-0952.txt" /tee

"ERROR 5 (0x00000005) Copying NTFS Security to Destination File"

Would anyone be able to explain why?

If I run it without the "U" the file appear to copy over fine with the ownership, but it does not copy over the NTFS permissions :/
