Very odd. I put XP on a few friends machines for them from here and wasn't able to use Windows Update through cable modem. WU page loads and offers to scan, but it just hangs at 0%, when it used to fly through it and give me the updates. Now I have found this is happening to my machine, which has it's own unique key. Has anyone had a similar xperience? I've changed the key, changed the IP of the cable modem, and WU is going to v4 of the update site.
