Hi
I have moved my Intranet server to DMZ within our physical network and i have opened Ports on Firewall for RPC and now i need to limit the dynamic RPC on both of my AD servers to communicate with my extranet server.Please let me know as how to safely configure this any information appreciated
Thanks

As RPC requires multiple ports (and not recommended to open a whole bunch of them on a firewall) I would suggest trying to setup the port assignments as per this MS technote
