WMI Dependency

  • Article

If your component is dependent on WMI for functionality then you should add three rules with the following parameters to your firewall rule group:

dir="in" protocol="6" lport="135" binary="%systemroot%\system32\svchost.exe" svc="RPCSS"

dir="in" protocol="6" lport="RPC" binary="%systemroot%\system32\svchost.exe" svc="winmgmt"

dir="out" protocol="6" binary="%systemroot%\system32\svchost.exe" svc="winmgmt"

If you require Asynchronous WMI calls then you will need to add an additional rule:

active="true" dir="in" protocol="6" binary="%systemroot%\system32\unsecapp.exe"
