Network Identification
 

My message is a little strange, I was wondering:

I am on a large network at my current place of employment, I am using Limewire all the time
and the Network Administrator used to get mad at me when I used Napster because he knew I was downloading MP3's.

He says he can keep track of the web pages I go to, and I can see that
because of proxyies and ****, but In any way, is the Network Administrator able to see what I am searching for or the names of the files I download?

I just want to know....For safty sake.

Thanks
Mani
