In my organisation I have my ISA 2004 server placed in between my internal Lan and the firewall.
 
LAN - ISA - Firewall - Router - Internet
 
All my Lan workstations will have their gateway point to the ISA server internal LAN IP.
 
All workstaions IE browser have also set it proxy server to ISA server internal LAN IP before it can surf the web.
 
All these has been running smoothly till recently my user alert me that,  no ISA server address is require to set at the workstaion IE browser, for them to surf the web.
 
I am really puzzle on this, as I am not an expert on this area. Any one can advise me on how to rectify this issue.

It is because of this. By default, ISA acts as a transparent proxy, meaning that all HTTP/HTTPS requests from internal clients that reach ISA will be deliverd to the web proxy filter, which will handle this request in the same way it handles any request that is explicitly using ISA as a proxy.

You can add firewall policy and restrict user authentications on ISA for internal clients.
