Hi,

I am currently setting up a network of about 10 - 15 PCs for an office. The PCs all run Win XP and a File Server exists which is running Win 2000. I would like to set up an e-mail server on the server and also virus scanning.

First of all is it worth upgrading to Win2003 Small Business Server?

The internet is accessed via an alcatel DSL modem, therefore each computer accesses this modem to access the internet. How could I go about setting up the server as a gateway meaning that all pcs must pass through the server before connecting to internet? and is this more secure? In that case would Antivirus software on the server cater for all the computers in the office as in viruses coming from the net?

Thankyou for your time.
