i definately worded that wrong, i did the normal xp commands, but on a 2nd pc off my router, and it worked but the first stopped working

i made sure it was a different ipv6 address too
i didnt do any special commands, just ipv6 install, and i copy and pasted the rest of the script and it worked, but then the first computer stopped working, any special reason why, or any insight?!?! thank ya
