I have 3 macs and a PS3/Xbox 360 all running on a protected wireless network at my house...our iPhones also use the network when necessary. Right now I am on the MacBook Pro, my iMac is on in another room, and all other devices are off. Usually under shared from this computer I just see my iMac in finder because I allow sharing between the 2 computers... but I noticed something odd that I've never seen before. Something else is showing up under "Shared". It looks like another computer and says "mac001b639f####" I didnt fill in the last 4 characters just in case this ends up being some sort of personal info that I shouldnt be sharing. Anyway - I have never seen this before. I clicked "More Info" and the only thing it says is that it's a PC Server. I can try to "Connect As" to it but doesnt let access any sort of info as Guest or as a Registered user. I just checked on my iMac and I do not see this from there, it's only showing up on this computer...I restarted and it's still there. Does anyone have any idea what this is? It's sort of freaking me out! haha. I attached a picture as an attachment.
