RPC is the Remote Procedure Call. This is a method that lets software on one
computer execute software on another computer. This isnt as dangerous as it
sounds at first. RPC is the "tool" that other software will use to do this.
RPC itself will not make attempts to access the net, another piece of
software is attempting to use RPC hence the net access attempt.
You need to be aware that a typical method used today is to use the inbuilt
networking on your PC to allow programs to communicate withthemselves. It's
common and entirely legitimate to have a one program running on your PC
try to connect to something via IP address 127.0.0.1. 127.0.0.1 is the local
loopback address of your own PC, and software will set up a server that
listens on this address for connections from programs running on the same
machine. Using the loopback address to allow multiple programs to communicate
is portable across many different operating systems.
So you need to know what caused RPC to attempt to connect to the net, and
which address it tried to connect to before you need really worry. It is
possible depending on just how you configured your machine for RPC to
request net access when it shouldn't. If you've blocked them and everything
is running you can rest slightly but you should check the firewall log file
and see where RPC was trying to connect to, possibly doing a "whois" on
the address that was saved.
