Dear Microsoft Customer,
On August 11, 2003, Microsoft began investigating a report of a worm, known
as W32.Blaster.Worm, that exploits the vulnerability addressed by Microsoft
Security Bulletin MS03-026. Microsoft released this critical security bulletin
and corresponding patch for Windows operating systems on July 16, 2003. While
some customers may not notice the presence of the worm infection at all on their
computer systems, typical symptoms may include Windows XP and Windows Server
2003 systems rebooting every few minutes without user input or Windows NT4 and
Windows 2000 systems becoming unresponsive.
If you applied security patch MS03-026 prior to the discovery of the
Blaster worm, your system is secure from the vulnerability that W32.Blaster is
using. For the most current information on determining if your systems are
infected and how to recover from the infection, please go to the following Web
site and perform the prescribed steps:
http://go.microsoft.com/?linkid=221445. This site will be
updated as more information regarding the W32.blaster worm becomes available.
Our goal is to provide you with the information and tools you need to help
run your company safely and reliably. When we become aware of these types of
vulnerabilities, it is our goal to share protection and remediation information
with you as quickly as is possible. In order to help protect your computing

that your computing environment will be safe from the worms and viruses that
occur.
Thank you,
