A firewall can block network traffic between your computer and other devices.

Microsoft Windows 2000 provides a couple of different built-in methods for controlling inbound network traffic. Many of these methods run as a process or executable under the credentials of a user account (a "user mode" process). TCP/IP filtering, commonly referred to as the "Windows 2000 firewall," is built in to the lower-level functions of the operating system (a "kernel mode" process). As a kernel-mode process, TCP/IP filtering works regardless of the user logged into the system. However, you cannot easily determine what traffic is being filtered and you may wish to disable the functionality altogether.


Step 1

Log in to the computer with a user account that is a member of the local "Administrators" group.
