When you generate a Distributed File System Replication (DFSR) propagation report by using the Distributed File System (DFS) Management snap-in or by using the DFSRAdmin command-line tool (Dfsradmin.exe), the following error appears in the report for some or all of the Windows Server 2008 domain controllers' SYSVOL share:
Error: Domain_name : cannot open test file on the member. The network path was not found.
The path for the SYSVOL folder that is stored in Active Directory contains the following group of characters:
\\?\When this character group appears in the path for the SYSVOL folder, the .NET manage code that is used in the DFSR administrative utilities cannot process the group correctly.
This issue does not affect Windows Server 2008 R2 domain controllers. Additionally, this issue does not affect Windows Server 2008 domain controllers where SYSVOL was migrated with Dfsrmig.exe. Files in SYSVOL will replicate without issue regardless of the domain controller’s operating system version.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
