A new version of the Ultrasound monitoring tool is now available for download. This version adds support for monitoring FRS on Windows Server 2008 and enables the use of SQL Server 2005 for hosting the Ultrasound database. No other new features have been added in this version.
Ultrasound is a tool for monitoring the File Replication service and does not monitor DFSR.
Important Note: To install the Ultrasound Windows Management Instrumentation (WMI) provider on an x64 version of Windows Server 2008, you must first install the hotfix that is included in Microsoft Knowledge Base article 954737.
Does the new version require an updated provider? I've just installed the new version and pointed it at the existing installed providers an it seems to be working ok.
You should be fine with the existing providers unless you want to monitor FRS on WS08 servers, in which case the updated provider needs to be deployed.
