Setting Up a Fixed Port for WMI
WMI runs as part of a shared service host with ports assigned through DCOM by default. However, you can set up the WMI service to run as the only process in a separate host and specify a fixed port.
The following procedure is an automated setup to allow WMI to have a fixed port. The procedure uses the winmgmt command-line tool.
To set up a fixed port for WMI
- At the command prompt, type winmgmt -standalonehost
- Stop the WMI service by typing the command net stop "Windows Management Instrumentation", or use the short name of net stop winmgmt
- Restart the WMI service again in a new service host by typing net start "Windows Management Instrumentation" or net start winmgmt
- Establish a new port number for the WMI service by typing netsh firewall add portopening TCP 24158 WMIFixedPort
To undo any changes you make to WMI, type winmgmt /sharedhost, then stop and start the winmgmt service again.
