In this module, you will evaluate and create Internet connectivity solutions using
Microsoft Proxy Server 2.0
Organizations connect to the Internet to provide Internet access to users on the private network and to allow users on the Internet access to private network resources.
The Internet connectivity solution must prevent unauthorized users from accessing private network resources.
Microsoft® Proxy Server 2.0® provides solutions to Internet connectivity requirements for Microsoft Windows® 2000 networks.
Proxy Server is a group of services that is not included with Windows 2000, but that runs on Windows 2000.
At the end of this module, you will be able to:
A proxy server
is a system that sits between the client applications (e.g., Microsoft Edge) and the connection to the Internet (server).
The proxy server intercepts requests to the Internet to determine whether the proxy server can act on the requests itself. This process filters requests to the Internet and thereby improves performance.
The proxy server can cache files that it downloads from the Internet for a client. For example, if a user requests the same page as another user, the proxy server can return the
version it is holding in its cache rather than send a request on the Internet. Proxy servers can also act as a firewall by filtering IP traffic by port or IP address.
Microsoft Proxy Server 2.0 performs all of the typical proxy server functions but includes extra functions such as Winsock proxy.
Proxy Server 2.0 replaces Winsock on the client machines so that Winsock-based clients (e.g., Windows 95) can use Winsock proxy to enable IP-type access even when the local network protocol is,
for example, IPX. You can also use Proxy Server 2.0 to hide your network's TCP/IP configuration
because the software lets you use any
TCP/IP address on your Intranet as the only proxy server IP address for use on the Internet.
Proxy Server 2.0 also includes the Socks proxy service for non-Winsock-type clients such as UNIX-based machines.
