Updating the SYSVOL Path
Applies To: Windows Server 2008, Windows Server 2008 R2
When you add or remove disk drives, the logical drive letters of the other drives on the system can change. If either your %systemroot%\SYSVOL\sysvol folder or your %systemroot%\SYSVOL\staging areas folder is located on one of the drives whose letter changes, Distributed File System (DFS) Replication cannot locate these folders. To solve this problem, you must update the paths that DFS Replication uses to locate these folders.
Before you update SYSVOL path information, you must stop the DFS Replication service and the Netlogon service. To change the path for the %systemroot%\SYSVOL\sysvol root folder and staging areas folder, you update path values in Active Directory Domain Services (AD DS). You also update the registry to change the path to the %systemroot%\SYSVOL\sysvol shared folder that is used by the Netlogon service. In addition, you must update the junction point that references the %systemroot%\SYSVOL\domain folder in the SYSVOL tree. The junction point that references the domain folder in the staging areas subdirectory (%systemroot%\SYSVOL\staging areas\DomainName) is updated automatically when you restart DFS Replication and Netlogon.
After you update the path information, when you restart DFS Replication and Netlogon, the new path values are initialized. To be sure that SYSVOL is not advertised on the network before the new paths are initalized, you must also modify the SysvolReady Netlogon parameter while the services are stopped. You can make this change at the same time you update the Sysvol Netlogon path in the registry.
