Well the one thing, if I dont change the 26 character hex more than once a week, i find a fourth machine in my network. And that is of course when I check. This hasnt been a problem in the past, but I am in an apartment bldg and new tenants move in all the time. So a recent move in is most likely the culpret.
I was even thinking of placing a 'bad' file in my shared folder labeled passwords. I dont think they would be amused I still have a copy of C.I.A by Cruel Intentionz kicking around on a backup disk somewhere.
