someones using my wireless network?

[kanecorp]

Sorry i didn't know where this post should go..

Anyways, i have both a wired and wireless network. All of a sudden about 2/3 days ago a computer started showing up w/ the name "Alfred Scott's Computer" in the Connect to Server window in OSx.2. On windows, in network places, "Alfred Scott's Computer" is not there at all. When i try to connect to the computer w/ the mac, it just saying contacting 192.168.1.153:548 timeout in *** seconds. It runs through the timer and i get error number -36.

This computer is the first computer to show up in the connect to server window while the others take at least 5 seconds to show. Also, when i try to ping or do anything with that address from "alfred scotts" computer, it tells me the address is dead.
Even when i use 128bit WEP encrytion on the wireless network, the computer is still there. Any suggestions on how to get rid of this guy (i have no clue who it is cause no one around here has the last name of scott) that would be great.
Thanks in advance

Try enabling WEP(encryption), but change your key/password to a non trivial one and see if it goes away.

it is probably a ghost - the guy may have got onto your network in the past, but now all you are seeing is the DHCP lease that is still available to him. This used to be a problem with early OSX - search for some posts around the subject to find a resolution.

If you want to keep people out of your network, I would recommend enabling MAC address restrictions. Any decent access point should support this. Of course, this is really only practical if your network is fairly small and static, otherwise it would get really annoying if you have to constantly update the list. Combine this with WEP, and the only way someone is getting in to your network is if they can crack the admin password, or spoof a MAC address. Both of those are quite unlikely.
