I am trying to restrict the port range that RPC uses on my monitoring server. I wish to be able to use whats up golds service monitoring feature (uses WMI) through my Cisco PIX firewall.
I have followed the microsoft KB http://support.microsoft.com/kb/154596
but to no avail. I have also used the RPCCFG utility as described in this KB http://support.microsoft.com/kb/908472
but with no luck. The reg entries get made but the server still attempts connections outside of my specified port range.
has anyone been able to get this to work? I have currently opened port 135 and 445 tcp and udp and my port range.
