Beta Information

This article discusses a beta release of a Microsoft product. The information in this article is provided as-is and is subject to change without notice.

No formal product support is available from Microsoft for this beta product. For information about how to obtain support for a beta release, see the documentation that is included with the beta product files, or check the Web location where you downloaded the release.


Consider the following scenario:
  • You use the DFS Replication service migration tool (Dfsrmig.exe) to migrate the SYSVOL share from the File Replication Service (FRS) to the Distributed File System Replication (DFSR) service in a Windows Server 2008 R2 Beta-based domain.
  • A disjoint namespace is configured in this domain.
In this scenario, the SYSVOL share migration process fails. Additionally, the following DFS Replication event log file is created after this problem occurs:


This problem occurs because the SYSVOL migration process from FRS to DFSR incorrectly uses the domain controller DNS name to build an NTFRS SYSVOL junction point name. However, the junction point name does not work in the disjoint namespace.
