Right, it seems this has come out of the blue. Im wondering if anyone can help me. We have a wireless network in the house (Netgear DG834N) with the following devices connected to the network (as of typing this): 1 x iMac 2 x Macbooks Im using a macbook myself, it shows the other macbook and the imac in the 'shared items' in the finder sidebar. However, recently its been showing: a 'PC server' named: mac001ff354bb00 our wireless network is password protected and secure. im curious as to what this item is???? anyone?? Is someone hacking? We live in a suburb (only around 5 house may be able to see our network as its draft-N), and still had this random device showing up when we had a Netgear DG834G. On a side note. We have a few other things in the house which are wireless enabled but NOT connected (or even switched on for that matter...): Another iMac 2 x PBG4 2 x Ipod Touches 2 x Sony Vaio's 1 x advent desktop 3 x sonos systems 1 x sonos controller 1 x PSP 1 x Xbox 360.
