You can use ie6setup.exe to download all the components from MS servers and move them to the target PC to do the IE 6 SP1 reinstall there. You can order it on CD already from MS as well, you can also see if you already have it on your latest Office CD, Norton CD, AOL CD, ...etc,....
DO copy ie6setup.exe and the support cab files to your hard drive and run the install/reinstall from there - just like a windows installation it helps tremendously when done from the hard drive. You are looking at about 75 megabytes of files for all platforms, are you sure you want all that in one file?
