Hi All,

   How do I close MSRPC (remote proceedure call) ports
Om Windows 7?  These a Remote Procediure Call (RPC),
which to me means ports and services for bad guys to
use.  Open RPC scare me.

The is Kaspersky End Point Security 10.1.0.867
with its firewall activated on Windows 7, 64 bit.

This Windows macine a Virtual Machine (KVM) sitting on
the RHEL host's local network.  nmap was run from the host:

Many thanks,
