WMI Proxy Requirements for Windows Host Data Collection
A WMI Proxy server is required for collecting data from Windows hosts.
• WMI uses DCOM for networking. DCOM dynamically allocates port numbers for clients. DCOM’s service runs on port 135 (a static port) and any client communicating with a host connects on this port. The DCOM service allocates the specific port for the WMI service. To set up a fixed port for WMI, see http://msdn.microsoft.com/en-us/library/bb219447%28VS.85%29.aspx.
• When installing the WMI Proxy, if the installer detects that Microsoft .NET is not already installed, it notes this dependency and then installs .NET for you. Microsoft .NET contains several necessary libraries.
• .NET Framework 4 is installed by default with Windows Server 2012. You must explicitly install .NET Framework 3.5 to support the WMI Proxy Service installation. You do not need to uninstall .NET Framework 4.
