Some folders or files are unexpectedly deleted on the upstream server after you restart the DFS Replication service in Windows Server 2003 R2, in Windows Server 2008 or in Windows Server 2008 R2

Consider the following scenario:

• In a network environment, you manage a file server that is running Windows Server 2003 R2, Windows Server 2008 or Windows Server 2008 R2.
• You use Distributed File System (DFS) Replication to back up files from an upstream server to a downstream server.
• You stop the DFS Replication service. Then, you move or rename some folders or some files on the upstream server.
• You restart the DFS Replication service.

In this scenario, the folders or files on the upstream server are deleted because of name conflicts with the downstream server.

For example, assume that you create the following folders on the upstream server in a network environment:

• CSROOT\FolderA
• CSROOT\FolderA\FolderB

Then, assume that you perform the following actions on the upstream server after you stop the DFS Replication service:

• You rename CSROOT\FolderA as CSROOT\FolderC.
• You create CSROOT\FolderA, and then you move CSROOT\FolderC\FolderB to CSROOT\FolderA.
• You delete CSROOT\FolderC.

In this example, you find that the move operation or the rename operation is not replicated to the downstream server after you restart the DFS Replication service. Additionally, the files under the FolderA folder are deleted on the upstream server when DFS Replication runs a conflict-resolution algorithm on the downstream server.

This issue occurs because of a logic error in DFS Replication.

Windows Server 2008 file information notes

Important Windows Vista hotfixes and Windows Server 2008 hotfixes are included in the same packages. However, only "Windows Vista" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows Vista" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

• The files that apply to a specific product, SR_Level (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table.
