Windows Tip Sheet
The Emperor's New Clothes
Win2003 SP1 packs in several new features -- and repackaged old stuff.
Reader Bryan Lucas wrote in to ask about some of the new (and renamed) services
in Win2003 SP1. Specifically, he noted several new and renamed services by comparing
servers after an SP1 install. Figuring out what these all do can be tough, but
I did some digging and came up with the following:
- Application Experience Lookup Service. Intended to automatically
apply software updates to programs to make sure they run on subsequent service
packs, mainly for compatibility reasons. Essentially, the service checks for
updates that correct compatibility issues with Windows patches or service
- DCOM Server Process Launcher. Launches Distributed COM (DCOM) processes,
and it’s required for a number of other services and processes to function
correctly -- including the Windows Firewall.
- Network Provisioning Service. Provides support for wireless cards
and wireless network configuration, and also for Wi-Fi Protected Access (WPA).
- Windows Firewall/Internet Connection Sharing (ICS). This one’s
easy -- it’s just the old Internet Connection Firewall (ICF) service
- Windows User Mode Driver Framework. This is part of Microsoft’s
next-generation driver model, which includes frameworks for both user-mode
and kernel-mode drivers. This service is for user-mode drivers. You’ll
actually notice it anytime Windows Media Player 10 is installed, too, because
the service is what provides synchronization with hardware devices like MP3
