Hi

I wonder if anyone is able to help me out here?

Our home private LAN is the standard 192.168.1.0/24 yet a device on the home LAN is regularly reporting the following:

Server Name: NAS01
IP Address: 192.168.1.50
Date/Time: 2011/12/10 14:26:13
Level: Warning
[Security] Access Violation from 192.168.47.1 with TCP (port=139)

Server Name: NAS01
IP Address: 192.168.1.50
Date/Time: 2011/12/10 14:26:14
Level: Warning
[Security] Access Violation from 192.168.17.1 with TCP (port=139)

There is no way 192.168.17.1 or 192.168.47.1 should be even entering my network and I'm unsure how to track it. Is there anything anyone can advise to track this down or tools on the router or otherwise that may assist?

Many thanks

Are any of your machines running virtual PC's?
