Someone living near you (within 100 metres) also has a wireless network. If you set yours up, you should be able to choose which network you want - make sure you give your network a meaningful name so that you can recognise it.\n\nIt would be worth finding who this person is, and telling them to enable wireless network security, and that you found their confidential information by mistake, so that they don't have malicious people using that information. And make sure you enable security on yours too.

If you are truly talking about the windows "Net Send" command the computer of origin is part of the message and message box.  You could then find that computer and possibly find out who was signed on at the time.

you can find out who the IP is registered to with a reverse IP lookup, although that won't necessarily lead you to the exact computer.\nhttp://psacake.com/web/eg.asp\n\nyou can also get an estimate of where that IP is located geographically, but it's not very reliable and your best hitting several sites found on google to get the best estimate of where the IP is currently located at.\n\nThat's the best you'll do just off an IP, you probably won't be able to find out who owns the computer that is using that IP address, maybe just the service provider.

If you mean is there a database or the info stored somewhere that would tell you that, then no.\n\nYou can add the person's ID to your messenger & watch to see when s/he comes & goes offline.

If you have the machine they are downloading from then you can just do a netstat to see where the connections are coming from.\n\nIf you do not know where they are downloading from then you will need to get a program like ethereal (packet analyzer) and set it up on a port on your switch that sees all local traffic.  It will record all of the traffic and provide analysis to show where the traffic is coming from.

Go to My Network Places, then depending on your operating system (i'm assuming you're using Windows XP, doesn't matter if its professional or home edition, 32 or 64bit..etc) Look on the left hand side of the box, and under the tab of Network Tasks, you'll see something that says "View network connections"\n\nClick on that and Viola! Your answer awaits =]

The IP ADDRESS at the top of full header. Will tell you if its the same person.

Look at the full headers of the email.  Look for the X-Originating-IP.  Search that IP # on http://www.arin.net/whois/  It will show you info on their internet service provider and you should be able to narrow down where the person lives based on that info.
