    Here's the results:

     

    Host xx.1.168.192.in-addr.arpa. not found: 3(NXDOMAIN)

     

    Ethernet and Wifi have 2 different IP addresses and the result was the same for both. I just used xx in place of the two distinct numbers in the result above.

    From Terminal issue

     

    ping -c3 XXXXX.local

     

    you'll get something like this

     

    ping -c3 XXXXX.local

    PING XXXXX.local (192.168.1.x): 56 data bytes

    64 bytes from 192.168.1.x: icmp_seq=0 ttl=64 time=0.042 ms

    64 bytes from 192.168.1.x: icmp_seq=1 ttl=64 time=0.073 ms

    64 bytes from 192.168.1.x: icmp_seq=2 ttl=64 time=0.071 ms

     

    The computer with IP (192.168.1.x) has the name XXXXX.local. Is that the IP of your iMac?

    Why are you using Ethernet and WiFi at the same time on the same computer?

    After the ping command, the results indicated the IP address that my WIFI is using for that computer.

     

    I had turned WIFI on previously since I was planning on logging on to the computer using WIFI devices, but I realize this is not necessary so I just turned it off to see if that was causing some of the problems.

     

    Once turned off, I tried the ping command again, and now it is indicating the IP address that Ethernet is using for the computer. However, I still cannot change the Computer Name with WIFI turned off. Same results.

    Leave WiFi turned off.

    Restart the computer. Try chaging the name again.

    It looks like you have 2 network instances, hence 2 names. Unplug one or the other connection for a while (like the rest of today) eventually one instance will fade away.

    I was getting hopeful that would solve the problem, but unfortunately it didn't

     

    It is reporting the right IP for XXXXX.local but the name can't be changed.

    Ken Loh Level 2 Level 2 (295 points)

    Hopefully you are correct. I will wait a bit and try later.

    Restart your router.

    You said the computers are in DHCP mode. Usually the DHCP servers store the name associated with a specif MAC address.

    Ken Loh Level 2 Level 2 (295 points)

    I guess I'm impatient and didn't wait too long...but I restarted the router, the cable modem and waited a couple hours.

     

    Unfortunately, it's still resulting in the same problem. Grrrrrr.....

    Ken Loh Level 2 Level 2 (295 points)

    The thing is...when I pinged for the XXXXX.local hostname, it specified that it was an unknown host, which I figured it meant I would be able to change it, but after trying, I got the same error message that it already existed. So I pinged again, and it displayed the same IP number that Ethernet is connected to.

    Ken Loh Level 2 Level 2 (295 points)

    Well, I let 24 hours pass and it's still not letting me use the name. I just don't get it?

    Had the same issue popping up today. Have a MacPro and MacBook Pro using the same Airport network. Issue popped up only on the MacPro. Resetting the name was no use. Changed the name completely, but after wake from sleep this also showed as name (2). After some experimenting, and considering that the 'Bonjour Sleep Proxy service' running on the Airport Extreme basestation maybe would register the computer names and could so be the cause, I disabled 'Wake for network access' in the Energy Saver preference panel.

    After changing the computer name again, putting to sleep and wake again, the new name was kept; so it appears this solved the issue.

    So I suppose the problem is related to that service getting mixed up. Don't now how to get this working correct again (didn't find any solution for resetting this service).

    Anyway, if you don't reuqire 'Back to my Mac' or 'Find my Mac' to work when your mac is asleep, this could help you out.

    Thanks for the suggestion, macroel. I tried it this morning but unfortunately the computer still wouldn't let me change the name. I could change it to anything else, just not the name that I want since it is specified that it's already in use.

    macroel Level 1 Level 1 (0 points)

    In my suggested set-up, just try another name and see if that works without getting the name (x); that worked for me. Didn't try with the old name, as I suppose 'Wake for network access' will in some way remember this and do the same annoying trick.

    As already said previously, think this service gets mixed up and didn't find a solution for restting it.

    See no issue to use a new name from now on.

    Succes, Ken
