hi, i have a macbook pro and a macbook air which i link together on my wireless network at home. i ussually screenshare both my macs. and the names for those macs appear on each other's sharing pane. (i.e my macbook pro's name on macbook air's sharing pane and vice versa) also, i have this "weird" pc server on my macbook air showing. under my mbp computer name. it is named as "macintosh-4". basically im sharing my macbook pro, and accessing screen sharing of my mbp from my macbook air. now, this "macintosh-4" does not appear on my macbook pro, only on my macbook air and any other macs which joins my network. i have found that if i turn sharing off in my macbook pro, my macbook pro dissapear from my macbookair's sharing pane, as well as the macintosh 4. when i turn that on again, my mbp appears and after few minutes, again macintosh-4 appear. i tried to get info on that & it shows as a pc server, and whn i get info on my mbp computer name, its showing mac server. i figure the problem is on my mbp, hv any of you guys out there experienced the same problem and know how to fix this? pls let me know. thnks. Ps- i have attached a pic of my macbook air's screenshot, on the sharing pane, it is showing my time capsule, my macbook pro (both names highligeted black) and the unknown macintosh 4.
