Automatic resolution policy for an offline file synchronization conflict does not work if the "keep all changes" setting is enabled in Windows Vista, Windows Server 2008, Windows 7 or Windows Server 2008 R2

Symptoms

Consider the following scenario:

  • You set up an offline file synchronization partnership between a network share and some computers that are running one of the following operating systems:

    • Windows Vista

    • Windows Server 2008

    • Windows 7

    • Windows Server 2008 R2

  • You set an automatic resolution policy to resolve conflict in the synchronization process.

  • You configure the policy to "keep all changes" when a conflict occurs.

    Note To do this, follow these steps:

    1. Click Start, type regedit in the Start Search box, and then press ENTER.

    2. Locate and then click the following registry subkey:

    HKEY_LOAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\NetCache
    3. On the Edit menu, point to New, and then click Key. Type SyncConflictHandling, and then press ENTER.

    4. Right-click SyncConflictHandling, point to New, and then click Expandable String Value. Type the path of the network share as the value name.
      
    Note If you use an expandable string (such as %appdata%), it must resolve to a UNC path and not to a local path. Otherwise, you may receive an "incorrect parameter" error during each sync.

    5. Right-click the value name, and then click Modify. In the Value data box, type 3, and then click OK.

  • You update a file at multiple locations when the file is offline.

  • You conduct a synchronization operation for the network share. It triggers a conflict in the synchronization process when it synchronizes the file.

In this scenario, the automatic resolution policy does not keep all changes for the conflicted file. Additionally, you receive an error message that resembles the following:

Cannot create a file when that file already exists.

Cause

The automatic resolution policy does not generate new file names for the conflicted file correctly when the conflict occurs in the synchronization process.
