Hi, I changed the network name of my iMac. Every now and again on my MacBook I get an error message 'There was a problem connecting to the server "my old iMac network name". I have checked the Keychain and to my knowledge I have cleared out all the old entries. Is it possible some app is trying to access it, how do I track down which one? So I know what I did to break it, but how do I fix it? Thanks.
