A Robocopy command updates DACLs incorrectly in Windows 7 or in Windows Server 2008 R2: "Article ID: 2639043 - Robocopy command updates DACLs incorrectly in Windows 7 or in Windows Server 2008 R2"

Assume that you use the following Robocopy command to perform file replication on a computer that is running Windows 7 or Windows Server 2008 R2:
robocopy /sec /mir
However, the Discretionary Access Control Lists (DACLs) for the files are updated incorrectly. This issue occurs even if the DACLs in the source location and in the destination location are the same.

Note When this issue occurs in a network environment that uses the Distributed File System Replication (DFSR) service, a very large DFS replication backlog is generated.
