I just now got the MMC crash on the other machine. How can I track this down and fix it so I can remotely manage the server's firewall? No relevant event log entries are produced there. When I try this from another machine on the network, MMC doesn't crash-but the Inbound/Outbound rule lists stay empty. The Windows Defender Firewall Remote Management rules are enabled: Name : RemoteFwAdmin-In-TCP DisplayName : Windows Defender Firewall Remote Management (RPC) Description : Inbound rule for the Windows Defender Firewall to be remotely managed via RPC/TCP.


and here's the Application event log entry:Īs expected, the Security and Maintenance control panel is useless for this.
