DeviceLock Service : Managing DeviceLock Service for Windows : Service Options : Policy Source(s)
  
Policy Source(s)
Use this parameter in conjunction with the parameter Use Group/Server Policy to specify the source from which DeviceLock Service receives its settings.
You can select one of the following options:
Local & GPO - DeviceLock Service either receives its settings from a Group Policy object or uses locally specified settings, depending upon the parameter Use Group/Server Policy.
Local & Enterprise Server - DeviceLock Service either receives its settings from a DeviceLock Enterprise Server policy object or uses locally specified settings, depending upon the parameter Use Group/Server Policy.
By default, an implicit option of Any is used to select the group/server policy source. This option will apply the first received policy - either GPO or Enterprise Server, after which the selection of the policy source will be automatically set - Local & GPO or Local & Enterprise Server, respectively.
 
Important: DeviceLock Service can receive its settings from the Acronis cyber protection system. In this case, the Policy Source(s) option setting has no effect and you must use the Acronis cyber protection service console to manage DeviceLock Service.
