Are you by chance running homegroup and IPv6 on the win 7 machine, and not on the vista box?

Ken J

thanks for your reply.

no i am not running homegroup. i have not yet created homegroup and please see the attached image of IPv6. i am not computer geeks so having very little knowledge in all this. main problem is my room mate bought another lappy and i want to share my net so that he can use wireless.
