hi mouser, thank you for your help.
still nothing worked, i used nlite to trim down xp, and from your google search link,
this person is having the same problem, but no solution.
i found that there is only one person that has the same problem when using urlsnooper,
this is the thread, judging from the date of the post, i dont think it is due to nlite, it could be the USB modem that i use.
i will image my drive and reinstall xpsp2 fresh see if it fixes it.
