Ports require for Remote GPO Update


  • Hello,

    I have my AD and servers in different networks separated by ACL rules. 

    I can manually do my GP Update, but when I use GPMC, I am getting an RPC error 


    1. My RPC ports are custom range (so I can setup ACL's) and they work fine (PortQuery tested)

    2. Referring to : : All expect the "TCP all ports, Winmgmt "

    Now, on Windows firewall I can find these, but from a Network Perspective, what does : "TCP all ports, Winmgmt " mean? What are the actual ports being used or can ACL rules be setup for this?
