Restricting RPC Traffic to Static Ports Range

If your BackNet traffic is filtered by firewall, you must reduce the number of ports, which can be used by the RPC traffic, as described in the KB article at http://support.microsoft.com/kb/154596.

To do that, execute the following commands on all Windows-based service nodes:

reg query HKLM\Software\Microsoft\Rpc\Internet

reg add HKLM\Software\Microsoft\Rpc\Internet /v Ports /t REG_MULTI_SZ /d 4000-4999

reg add HKLM\Software\Microsoft\Rpc\Internet /v PortsInternetAvailable /t REG_SZ /d Y

reg add HKLM\Software\Microsoft\Rpc\Internet /v UseInternetPorts /t REG_SZ /d Y

Note: The first command can fail if the key does not exist. In this case, ignore the failure.
