examine any third-party software firewalls or endpoint protection software on the existing domain controllers and firewalls between the existing domain conrollers and the domain controllers that are running Windows Server 2012. Make sure that their rules enable the following:
TCP/IP – port 135 – RPC/DCOM/WMI endpoint mapper (RpcSs)
TCP/IP – all ports – Asynchronous callback WMI client (Unsecapp)
TCP/IP – all ports – Windows Management Instrumentation service (Wmimgmt)
But then I know how to allow port 135, but I am confused as to how to set the two others: Unsecapp and Wmimgmt) .
I have set a rule to let the traffic 135 TCP through the firewall, but I am not sure how to make the other two rules.
