Cache server hostname source & LocalPolicyMerge setting
hi In our organization we have the LocalPolicyMerge setting set to false thus blocking all standard or custom locally created inbound MDE firewall rule. Outbound does not have any such restriction. ...
In case of you are speaking about clients that are not getting MCC Server by DHCP option.
Since local policy merge is disabled, you’ll need to push a complete set of firewall policies to the client from your management platform.
