Installation Tips for Service Pack 2
When installing Service Pack 2, HP recommends the following considerations be made:
· To ensure that Symantecs Norton Antivirus works properly with Windows Firewall in SP2, please run
NAVs LiveUpdate to receive all the latest definitions and updates. If you are running Norton Antivirus,
version 2002 or earlier, we strongly recommend you upgrade to the latest version.
· T.V. Media (TvMedia.tvmbho) from Total Velocity Corporation may cause Blue Screens or other
performance issues when SP2 is installed. Before upgrading to Service Pack 2, contact Total Velocity
Corporation for a software upgrade, or uninstall T.V. Media.
· Before upgrading to Service Pack 2, install Microsoft Update QFE Q835409 which addresses a critical
issue with the Windows XP System Restore feature. Failure to install the update may prevent System
Restore from working correctly after the upgrade is complete. The QFE can be done in one of several
ways:
o Download and install SoftPaq SP28454 from the HP website; or
o Download all critical fixes (except SP2) from Windows Update
Windows Firewall
Programs that connect to the network or internet as part of their general functionality may not function as expected
after an upgrade to SP2 due to a new feature, Windows Firewall. Most programs will prompt the user to add the
program to the Firewall Exception list the first time it is run after an upgrade. However, some programs may need to
be added manually, or may need additional ports added to the Exception list. For more information on Windows
Firewall, please refer to Microsofts Windows Firewall website. For Troubleshooting tips, please refer to Microsoft
Knowledge Base Article # 875357.

Active X
Programs and websites that utilize Active X may not function as expected after an upgrade to SP2. This is a result of
stronger security around Active X. SP2 will block Active X installs, and on most web pages will notify the user with
an Information Bar that will also allow the user to force an Active X install. For more information on how programs
that use Active X can work in harmony with XP SP2, please refer to the Microsoft documentation at:

Data Execution Protection (DEP)
Windows XP SP2 uses a new feature to prevent the execution of code from data pages. This feature is known as
Data Execution Prevention (DEP), No-Execute, or Execution Protection. When a program attempts to execute code
from the protected data pages, the DEP feature closes the program and displays an error notification. This feature is
designed to prevent damage from viruses and other security threats. Other programs may also display this error,
even if the code is not malicious. For a detailed description of the DEP feature, please refer to Microsoft Knowledge
Base articles # 875352 and 875351.
This feature is disabled by default on HP Commercial Desktop products. It can be enabled using the HP Computer
Setup (F10) Utility.
