So, I open up iTunes just now and I see "Kyle [LastName]'s Music" as a music source in iTunes. Fantastic, but: 1. I know no such Kyle 2. I'm on my home wireless network, which has MAC address filtering turned on (though I know, this isn't foolproof). WEP is off (sorrysorrysorry! I can't remember why we decided not to turn this on ... is there ever a valid reason to leave it off?) 3. Here's the weird part ... the wifi router's log doesn't indicate any new client has received an IP lease. I can post the log here if anyone wants to see it, but it's pretty readable, and it looks like all the MAC addresses and computer names belong to us. So, what does this mean? Is this Kyle guy actually on our network? If so, how did he get on (MAC address spoofing? If so, wouldn't he be leet enough to change his iTunes shared name to something other than his full name)? If he's not on our network, how can I see his iTunes? FWIW, I can't play any of his songs -- I get error -3259, which claims that a firewall someplace is blocking the connection. (The firewall thing is likely -- we have a hardware firewall and also the firewall in the wireless network on.) So, who wants to try and help me figure out the answer to any of that? Thanks in advance.
