I prefer a 2x4 with rusty nails driven through personaly..and watch the dict links it may lead people to the monastery

as for the original question I doubt it was a malicious attach as the domain and the system had the same name see more like a user screw up...do you have any one in your company named Carrie they would probably be the culprit… if not do you have a WAP..if so secure it you are broadcasting further then you think.
