I have small workgroup having 10 computers in my office. I do some personal work in office like using yahoo messenger, checking personal e-mails and some online banking site. But how does one of my senior knows it? I do everything lonely and securely so that nobody in the office knows it. But he knows everything about my sites I visit everyday. He has also cracked my yahoo password twice. He even knows it, if I open any site for a few seconds in a day.

My question is, is there any website or any program which can track the details of LAN computers?

I think he is using that to find out everything about my computer. I use win 2000 with service pack 4 and he uses win xp sp2. Windows defender is also installed in my computer.

Any help on this would be highly appreciated.

Thanks

Lets me rephrase the entire problem again.

Company expand so fast that the IT infrastructure is not fast enough to cater high volume of traffic; the initial design is not scalable. The number of new branch offices setup caused the company pay a high price in the leased line communication.
Salesman and management staffs dial into company networks via 56K modem to access the database server and update the sale order. All the branch offices access the internet via HQ and download email via the external POP3 email server.
Plan to revamp their IT infrastructure and reduce the leased line access cost. Here are some of the feedbacks consolidated from the various country managers and local salesman.
1) The email downloading and sending is very slow. They receive a lot of spam email this caused their individual mailbox quota use up very fast.
2) The sales and marketing departments need to access the internet to search for latest news and market trends. But the internet speed is very slow. These people are irritated by spywares and popup often.
3) The File transfer and Database access is very slow even in the local area networks.

I decided to put the real network cum equipment diagram of my current company as I believe this will at least give INSIGHT in solving the problem.

Please visit the website http://www.hgym.photosite.com
for the diagrams which are network diagram and equipment diagram.

Now I plan to improve the IT infrastructure to cater for future expansion up to 10 countries. SAP will be implement to automate the overall company operation. Also expect 3rd party to access their server to submit and view sale order.

I also plan to redesign the network so that it is high available, scalable and secure.

Any suggestion and opinion? What is your comment after looking at my network and its insfrastructure (from the diagrams on http://www.hgym.photosite.com )
Any improving needed?
