Windows XP Professional has all of the
necessary software that you need to use your ResNet connection to
connect to the Internet. TCP/IP is the protocol, or language, used
by Internet Applications. This document describes how to set up Windows
XP Professional for TCP/IP access. While ResNet will support Windows
XP Home Edition, we strongly recommend that you purchase the Professional
Edition instead.
Make sure your Ethernet card is properly installed and your 10BaseT
cable is plugged into the proper wall outlet.
The instructions below are for the default configuration. If you
have made changes to your system, the steps needed may be slightly
different.
Installing the TCP/IP Protocol
You may have installed the TCP/IP protocol when you installed Windows
XP. To check, open the Start Menu and choose "Control Panel".
Select "Network and Internet Connections" and then
"Network Connections" You should now see a window
similar to the one below.
IMPORTANT: If a "Network Bridge" is present,
right click on it and select "Delete". This option
may prevent the network from working properly.
Right-click on "Local Area Connection". Choose
"Properties" from the menu.
If TCP/IP is already installed (it is by default), it will appear
in the list of installed protocols. If this is the case, you should
skip to the "Configuring TCP/IP"
section of this document below. If it is not in the list, you will
need to install it.
To install the TCP/IP protocol,
- Click on the "Install" button.
- Double-click "Protocol."
- Double-click "TCP/IP."
- Insert the Windows XP CD-ROM if prompted to do so.

Configuring TCP/IP
To configure the TCP/IP protocol, go to the Network Connections
window (open the Start Menu and choose "Network Connections")
and right-click on "Local Area Connection". Choose
the "Properties" from the menu. Highlight the TCP/IP
entry and press the "Properties" button.

Check both the Obtain an IP address automatically and the
Obtain DNS server address automatically radio buttons. Click
on the Advanced... button at bottom.
STEPS 5 and 6 are extremely important.
Click on the DNS tab at the top of the screen.
Locate the check box next to Register this connection's addresses
in DNS towards the bottom of the screen. If the box is checked,
uncheck it. If it is already unchecked, leave it alone.
Click OK to close this dialog box, and close the Network
Connections window. You may need to reboot your computer for the
changes to take effect.
