Windows XP Service Pack 2 FAQ
IMPORTANT NOTICE: IT Services recommend and support Service Pack 2 for users on campus.
Introduction
Microsoft has released Windows XP Service Pack 2, their latest update to the Windows XP operating system. This differs from the other Microsoft Service Packs in that it is not just a collection of bug-fixes and security updates: it alters the way that Windows XP works and adds new features. In effect, it upgrades Windows XP to "Windows XP Second Edition" and should be treated as a new operating system by system administrators.
Who should install this?
Important: Users connecting to the Internet via modem or broadband to an Internet Service Provider (ISP) should check with their ISP before installing Service Pack 2 . The security methods used by the ISP may conflict with those of Service Pack 2 and prevent you from connecting.
There are a number of new security features in the service pack, which can be of benefit to home users if configured correctly.
What does it contain?
Microsoft have documented this on their website; a good starting point can be found on the Microsoft XP Service Pack 2 web pages. In essence, it contains the first couple of years' worth of updates released via Windows Update since the release of Windows XP in 2001, plus a new Security Center containing an updated software firewall, DirectX 9.0c, Media Player 9 (note that Media Player 10 is now available) and the Internet Explorer 6 Pop-up Blocker.
Who should not install this?
Users with PCs that are close to the minimum spec for Windows XP may notice a performance degradation, mostly due to the included software firewall and automatic update checking. However, even if you disable these two features there is a further feature called DEP (Data Execute Prevention), which cannotbe disabled. This monitors all of your core programs and attempts to block casual exploits in their operation.
Do I need to install Service Pack 1 first?
Service Pack 2 contains Service Pack 1; you do not have to install it first. Incidentally, it also contains DirectX 9.0c, Media Player 9 (note that Media Player 10 is now available) and a new version of Internet Explorer which blocks pop-up windows.
Does it work for both Home and Professional editions?
It works for both Home and Professional editions, and also Windows Media Centre edition.
How do I install Service Pack 2?
See our install guide for non-campus users in the Installing Windows XP Service Pack 2 web page.
Since installing Service Pack 2 my emails hangs for 5 seconds before being sent. Why is this?
The reason for this is that you have the Windows XP Firewall enabled. Either disable the Windows Firewall, or add a new firewall exception to TCP port 113. The reason for this wait is because the Windows XP firewall doesn't allow for identity checking, which our (non-Microsoft) mails servers require in order to minimise the amount of spam which you receive.
I want to enable the Service Pack 2 firewall. How can I do this?
When you install Service Pack 2 the Windows firewall is enabled automatically. If you don't want to use it (you may already have your own, for example Zone Alarm), you have to manually disable it from the Windows Control Panel. Instructions for disabling or configuring the Windows firewall may be found in the The Windows XP Firewall web page.
Since installing Service Pack 2 my application has stopped working. What can I do about this?
Microsoft have acknowledged problems with some applications. You can see their recommendations in the The Windows XP Firewall web page.
