Re: Locate IP address location/owner
Another thing u can do is contact the sites that he posted the picturs on and tell them what happened. Maybe they'd be sympathetic. I don't think the ISP is going to do anything unless u get some lawyer and have them write a letter for you.
DHTN, there's various ways you can get the IP address. Setup auditing on your Windows XP machine and then check the Event log (security) to see who accessed what. You can also look at the firewall logs etc.
