I was doing some reasearch and trying to understand why not disable RPC. Can someone explain to me or point to a link. So i can understand hwo to secure RPC(disabling, firewall blocking port 593 i think) I know that i need to keep up with patches and all that. Some of articles on the net said no to disable it cause your system wont run in a stable manner after that, why?. Any help would be appreciated.

Thanks
