Ultrasound is a monitoring and troubleshooting tool for the File Replication Service (FRS). FRS is a legacy technology that replicates files and folders that are stored in Distributed File System (DFS) folders or in the System Volume (SYSVOL) folder on domain controllers.
Note: FRS was replaced by DFS Replication for replicating DFS folders in Windows Server 2003® R2, and for SYSVOL replication in domains using the Windows Server 2008 domain functional mode.
Ultrasound measures the health of FRS replica sets by providing health ratings and historical information about the replica sets. Ultrasound also allows administrators to monitor the progress of replication and detect problems that can cause replication to become backlogged or stopped.
To deploy the Ultrasound WMI provider on an x64 version of Windows Server 2008, the hotfix KB954737 must be installed (this fact is also mentioned in the release notes).
