Best Practices for Sysvol Maintenance
- Net Logon shares. These typically host logon scripts and policy objects for network client computers.
- User logon scripts for domains where the administrator uses Active Directory Users and Computers.
- Windows Group Policy.
- File replication service (FRS) staging folder and files that must be available and synchronized between domain controllers.
- File system junctions.

|Sysvol Folders||Junction Point Location|
Junctions graft the namespace (any bounded area in which a specific name can be resolved) of the destination file system location to an NTFS volume. An underlying reparse point permits NTFS to transparently remap an operation to the destination object. As a result, if you modify the data in the Sysvol structure, changes occur directly on these physical files. Additionally, if you perform a cut-and-paste operation or a copy-and-paste operation with these folders in the Sysvol structure that contains junction points, the cut-and-paste operation or the copy-and-paste operation occur in the junction point information.
Microsoft recommends that you avoid performing a cut-and-paste operation or a copy-and-paste operation on the Sysvol structure, especially when you perform the paste operation on the same server. If you perform a cut-and-paste operation or a copy-and-paste operation on the Sysvol structure, a copy of the junction point information is created. This does not result in a copy of the actual data. Instead, a copy of the junction point information only is created. If you modify any of the files that appear in that folder, you modify the source files directly.
Microsoft recommends that you do not modify the Sysvol structure. This recommendation also applies to backup and restore operations of the Sysvol structure. By default, if you back up Sysvol by using NTBackup.exe, the backup file includes a backup of the folder's junction point information. If you restore a Sysvol structure from a backup file to a different location on the same server, do not restore the junction point information. To do so, use the advanced restore options.
Microsoft recommends that you do not modify any files directly to Sysvol without understanding the behavior of junction points and how these points affect Active Directory in your enterprise.
Note Under Windows Server 2003, if you copy %systemroot%\SYSVOL, you do not copy the junction points. However, under Windows 2000, if you copy %systemroot%\SYSVOL, you do copy the junction points.
