PC sending packets to a non-existent local IP address.

Posted on 2014-08-19

I have a PC on the network which is occasionally trying to contact a certain address ( But this address does not exist on our network.  I looked in the installed programs of this PC ( Windows 7 OS). There is nothing suspicious on it. What is the best way to find out what process or service is doing this? RSA Envision picked up these packet transmissions. Any suggestions or ideas would be greatly appreciated. Thanks

    Run the command

    netstat -a -b   (by the way, you should run it with Admin rights)

    it will show you what process are connecting to the remote addresses.

    Also you can use Wireshark to capture the packets and see the details of connection.

    Hope this helps.

    RSA Envision could give you details. Do you have the log?

    Anyways, Wireshark can be downloaded from here

    Once it is installed, start capturing the network Traffic (select the right interface).

    Then, filter     ip.addr==

    it may well be the address of a printer or another network device, nothing harmful. have a look into device and printers on the pc.
