http://serverfault.com – I have joined new job and here its the big govt department. They have server 2008 as server with proxy server for all internet access. Now my home internet connection is dialup and i will get broadband coonection within 2 months. Now i download lot of stuff and i want to do the same feom my work pc. Now i want to know that doe server logs which site i have visits an dhow much data i have downloaded from each site. The other option i am thinking is that i have the virtual server wher ei have unlimited Bandwidth. So what i can do is download my stuff to my virtual server and then from there (HowTos)
