MS has a support article on it ... about 1 yr old. Gardenweb link at bottom. but it also says The ISATAP adapter encapsulates IPv6 packets by using an IPv4 header. This functionality enables the client to transport IPv6 traffic over an IPv4 infrastructure. ....... I'd probably try rebuilding the Tcp/Ip stack... A standard fix for problematic network connection problems anyways. http://support.microsoft.com/kb/299357 (MS Fixit) Here is a link that might be useful: MS Support 'ISATAP adapter code 31'

You would probably eliminate the problem, by going down to the version of firefox, you had before upgrading. Your system is older, and some of the requirements for the newer version of firefox, you just may not have on that computer. :-)) I also run XP, and I use firefox. I am running version 9.0 and it works perfectly. I could go a couple updates higher, but, when something is working great, best not to mess with it, especially on an older system. Also, notice above recommendations to update your IE. You should be aware, that some XP computers will not run IE8 very well, and some will. Most will run ie7 without any problems. Please check all system requirements when you decide to update or download something on a system that is using XP and enjoy using that computer for a long time yet. Good Luck to you.

First, thank you all. ravencajun, I especially thank you for your simple explanation of ISO. zep516 - exactly what I needed. I wasn't sure about 32 or 64; but went with 32 and if that hadn't worked would have gone back and gotten the 64. I was able to boot up from the disk; got the c prompt and put in chkdsk /r. It found 2 errors and fixed them. Then I exited, and opened in safe mode. Itried to uninstall the Silverlight, but it has an error in it. I decided not to go to MS to correct it so that I could uninstall it, since the LT was working and I wouldn't be using that program. I went to start/turn off/restart taking out the CD and the LT started up and is working fine. Now I am going to the post about AVG since that is on the LT and I don't want to go on line until I am sure I can without the bad AVG update. Thank you all so much for your patience and explanations!
