Use this link. Very informative. This might not be as easy as just installing a piece of software, but you'll never have to worry about software timing out, or reg keys that get left behind, etc. I am personally using this style on my current machine. In short, it directs everything to your own hard drive, where it is assigned no IP address...or something like that (I did it months ago...my brain fails me tonight...!) Might not be for everybody, but a nice read just the same.
