First I want to say thanks for a lot of information, which this forums provide it to us. I have issue in my network, actually I am network security administrator in my network and I am using PIX and IPS in my side. I am filtering all Internet request from my Firewall but I faced last days some end user installed and used Internet from broadband USB modem. I know there is week from our technical support they did nit disable local administrator account or maybe they already installed the broadband USB modem for the end user. My question now how can I know if there is Internet connection active in my network from other source like broadband USB modem or dialup connection.
Thanks for your time to read my issue.
