This is what I meamt in an earlier post (see the bold text below) why Microsoft wants to control the ditribution of SP2. I haven’t been able to try the described utility yet.
My advise would be to just wait for the windows update distribution.; that way you’re sure you get the right stuff downloaded.
From Lockergnomie Ben Brady: “Just thought I’d drop you a line to let you know that I have released the new XP SP2 Retriever utility. There have been numerous reports of people posting XP SP2 to P2P networks and there have been some who have become the victims of trojans and other malware. This utility is designed to keep that from happening as it downloads the XP SP2 network installation directly from the Microsoft web”.
