iMac's former name appears on sidebar

[fscarpa]

I've changed the name of my computer (Preferences -> Sharing -> Computer Name) and since then on Finder's side bar (under shared), the old name appears as if there was another computer in the Network. Of course if I click on it, I get a "Connection Failed". It's a ghost computer!
Any ideas on how to fix it? (I've already turned off and on the computer).

Cant you just drag it out of the sidebar. Or you could always go into Finder prefs, remove the "Sharing" tab completely, reboot and reenable it and see if that helps

I tried it all and nothing seemed to work. Then today it suddenly disappeared...
Strange...

Did you happen to turn off all your computers or power cycle the hub/switch/router the computers are all networked through? One of those computers probably had the old name cached somewhere and caused all the other machines on the network to also see the old name until they were all powered off or the switch had a chance to clear it on the backend.
