Change the SYSVOL Netlogon Parameters

Applies To: Windows Server 2008, Windows Server 2008 R2

When you are relocating the SYSVOL tree, you can use this procedure to update the registry parameter that the Netlogon service uses to discover the path to the SYSVOL\sysvol shared folder. Netlogon advertises the shared folder location based on this registry entry. The default value in this entry is Drive:\%systemroot%\SYSVOL\sysvol. If you move the SYSVOL tree to a different folder or drive, or both, or if only the drive letter changes as a result of hardware updates, you must update this Netlogon parameter.

When you update the SysVol Netlogon parameter in the registry, you must also change the SysvolReady Netlogon parameter so that SYSVOL is not advertised until all new path values have been initialized.

Membership in Domain Admins, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at Local and Domain Default Groups (

To change the SYSVOL Netlogon parameters

  1. Click Start, click Run, type regedit, and then press ENTER.

  2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters.

  3. Right-click SysVol, and then click Modify.

  4. In the Value data box, type the new path, including the drive letter, and then click OK.

  5. Right-click SysvolReady, and then click Modify.

  6. In the Value data box, type 0, and then click OK.

  7. Close Registry Editor.


The path in the SysVol registry entry points to the sysvol shared folder, which is located inside the parent SYSVOL folder that is under the root (by default, Drive:%systemroot%\SYSVOL\sysvol). When you update the path, ensure that it still identifies the sysvol shared folder within the parent SYSVOL folder. If you have moved the SYSVOL tree, the root folder will change. Be sure to also change the drive letter to its new value if this has changed.
