Remote WMI relies on Windows Firewall settings incorrectly even if a third-party firewall is enabled


Assume that a third-party firewall is installed and registered by using Windows Firewall to take ownership of Firewall policy management. Remote Windows Management Instrumentation (WMI) connections are blocked even though the third-party firewall that owns the policy is configured to allow the connections. 

This issue occurs in the following operating systems:

  • Windows 10 Version 1511
  • Windows 10
  • Windows 8.1
  • Windows Server 2012 R2
  • Windows Embedded 8
  • Windows Server 2012
  • Windows 7 Service Pack 1 (SP1)
  • Windows Server 2008 R2 SP1


This issue occurs because the DCOM API doesn't honor the third-party firewall when it queries the firewall settings.


To work around this issue, run the following command at a command prompt to enable WMI traffic:
netsh advfirewall firewall set rule group="windows management instrumentation (wmi)" new enable=yes 


Microsoft is researching this problem and will post more information in this article when the information becomes available.
