Setting Up a Home and Office Network
Network Setup Wizard
The Microsoft® Windows® XP operating system provides a Network Setup Wizard to guide you through the process of sharing files, printers, or an Internet
connection between computers in a home or small office.
1. Click the Start button, point to All Programs® Accessories® Communications, and then click Network Setup Wizard.
2. On the Network Setup Wizard welcome screen, click Next.
3. Click Checklist for creating a network.
4. Complete the checklist and required preparations.
5. Return to the Network Setup Wizard and follow the instructions on the screen.
Internet Connection Firewall
The Internet Connection Firewall provides basic protection from unauthorized access to the computer while the computer is connected to the Internet. The
firewall is automatically enabled when you run the Network Setup Wizard. When the firewall is enabled for a network connection, the firewall icon appears
with a red background in the Network Connections section of the Control Panel.
Note that enabling the Internet Connection Firewall does not reduce the need for virus-checking software.
For more information, see the Windows Help and Support Center (Microsoft® Windows® XP).
Data Execution Prevention (DEP) Technology
Your computer may include data execution prevention (DEP) technology, which is supported by Microsoft® Windows® XP Service Pack 2 (SP2). This feature
prevents the execution of code in memory regions of the computer that are set aside for data storage. When an attempt is made to run code from an area
marked as data storage, DEP helps the computer to detect this action, intercept the code, and raise an exception to prevent the code from executing. If your
computer supports the DEP technology, it is enabled by default for essential Windows programs and services.
For more information about this memory protection technology, search the Microsoft Knowledge Base website for Knowledge Base Article #875352 for details
about the data execution prevention (DEP) feature.
If you receive a "Data Execution Prevention" error message in Microsoft Windows XP Service Pack 2, see Microsoft Knowledge Base Article #875351.
