Major Vulnerabilities in the Windows Operating System

Network Security strongly advises Windows users to immediately install patch MS04-007.

How to Patch Your Windows System:

  1. To prevent your machine from being compromised while you are applying the patch, Network Security encourages users to implement port filtering described at

  2. In most cases, you will be able to use Microsoft's free Windows Update service to patch your computer. From your Windows computer, using Internet Explorer, go to and follow the instructions for obtaining all Critical Updates. The easiest way to accomplish this is to continue running Windows Update until there are no more critical updates left to install. If there are several of them to install you will likely need to reboot more than once. Please note: Windows 2000 Service Pack 4 may break older versions of Kerberos. This can be fixed by installing the latest version of Kerberos.
