This object discovers volumes hosting replicated folders on computers running Windows Server 2008 R2.
This object discovers volumes hosting replicated folders on computers running Windows Server 2008 R2. It does so by querying the DfsrVolumeInfo WMI class.
Users with Author or Administrator permissions in Operations Manager can use overrides to change the following parameters:
IntervalSeconds controls how often Operations Manager runs the discovery process.
Timeoutseconds controls how long to wait for discovery to complete.
