Local host name already in use

I routinely get a message saying "local host name is already in use on this network. The name has ben changed to...."

Is this a home network or a workplace network?
If you open up terminal.
Go to Applications> Utilities> Terminal and type in hostname
what comes up?

  • Keep getting error message about my computers local host name already in use

    I keep getting the following random error message popping up on my desktop. The last time it said the same thing, but imac-2.local? Haven't changed anything to my knowledge.
    This computer’s local hostname “glen-cumbuss-imac-2.local” is already in use on this network. The name has been changed to “XXXXX-XXXXXXX-imac-3.local”.

    Sometimes this message means that you have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. Disconnect the Ethernet cable or turn off Wi-Fi.
    If that's not the issue, shut down any virtual machines (Parallels, VMware, or VirtualBox) that are running.
    Sometimes there's no identifiable reason for the behavior.
    Rename the computer in the Sharing preference pane.

  • Local host name  message pops up on start up

    I've started getting message  on start up saying "local host name is already in use, do  you want to change"
    this just began happening.
    what does this mean and how can i fix it from poping up?
    thanks

    Hey R%%^Y,
    Thanks for the question. It sounds like another computer on your network may have a similar local hostname. You can change your hostname in System Preferences > Sharing:
    OS X Mavericks: Find your computer’s name and address
    http://support.apple.com/kb/PH13790
    Local hostname: Your computer’s local hostname, or local network name, is displayed on your local network so others on the network can connect to your Mac.
    Your computer’s local network name is displayed beneath the computer’s name at the top of Sharing preferences.
    The local network name is your computer’s name with “.local” added, and any spaces are replaced with hyphens (-). For example, if your computer’s name is My Computer, your local network name is “My-Computer.local.” Local network names are not case sensitive, so “my-computer.local” is the same as “My-Computer.local.”
    Thanks,
    Matt M.

  • New Local host names

    I am brand new to macs and still don't have a lot of it down yet, so this question may seem pretty simple.
    When I turn on my mac, it has started telling me that my local-host-name is already being used and that I need to use a new one. For example:
    XXXXXXXXX-2.local is already being used, please use XXXXXXXX-3.local etc.
    That's not the exact wording but the basic idea of it. I think that it's affecting my ability to connect to my external harddrive through my router.
    Thanks,
    macbook   Mac OS X (10.4.9)  

    My computer has a name unique to my network "John Smith's Computer" however this message appears below
    Other computers on your local subnet can access your computer at john-smiths-computer-5.local
    Is this alright? I would think that this isn't how it should operate. Is there a way that I can close/log-off of x-x-computer-5.local?

  • Sun would like your help with the "System Name Already In Use"  error

    A couple of users have reported getting an erroneous "System Name Already in Use" error when re-registering a system after a fresh Solaris re-install. We'd like your help in tracking down this problem.
    The scenario is this:
    * Install Solaris 10 and register with updatemanager,
    * Wipe out the installation and re-install Solaris.
    * re-register with updatemanager.
    The system erroneously reports that the system name is already in use. It is supposed to detect a duplicate registration of the same system.
    We have not been able to reproduce this error in our lab.
    If this has happened to you, would you let us know at [email protected]?
    Here are the things that we would like to ask of you:
    * If you run "updatemanager -debug" if will create a log file /tmp/basicreg<timestamp>.log.
    * Details on the exact hardware you have (make/model/configuration).
    * Details on the steps you took to get to the bad state. REALLY detailed!
    Thanks!
    Based on what we know now, we believe you can work around the issue by either:
    * Changing the host name and re-registering.
    * Creating a different user account and registering the host to that account.
    Some previously-posted workarounds are known NOT to work:
    * Wait 24 hours and try again.
    * Do some "ccr" incantations and try again.

    Hi,
    Can you drop me an email as i am a sun employee and i will be able to check if the swup frontline team have received any support cases on this issue and then we can work with you directly to resolve the issue.

  • DNS or Local Host Name Issue

    I have an iMac, 10.6.2 that continues to get a duplicate IP address error. I have determined that this iMac is seeing itself as another machine on the network, hence the duplicate IP error. I have changed the local host name under system preferences -->network (and in sharing) to imac10.6.2-username However, on the WINS tab of system preferences-->network the computer name shows as imac 9B14C4. I have manually changed this on the WINS tab and but it doesn't actually change it. I have flushed DNS and used the scutil--gethostname command to no avail. Additionally, this iMac does not show up when browsing the network from any machine on the network. All other Macs here do. Any suggestions?
    Message was edited by: EricWeiner
    Actually I can browse to it through the network by either the DNS name or the WINS name, even though I tried to make them the same.

    I use a Mac mini as a small AV server, and have exactly the same issue. Message keeps popping up at least once a day. Changing name in Preferences doesn't make any difference. After a few weeks it's gone from 'Centerstage' to 'Centerstage-8'. I even formatted the HD and installed Leopard and after that Snow Leopard. Didn't solve anything. Very irritating. Apple only recognizes this as a Mac OS X server issue.
    Help.

  • Error occurred in deployment step 'Add Solution': The definition specifies a claim provider with a name already in use.

    Hi,
    When i am trying to deploy sharepoint 2010 application in VS 2010, i am getting the below error:
    "Error occurred in deployment step 'Add Solution': The definition specifies a claim provider with a name already in use."
    How to fix this?
    Thank you

    You can use:
    $provider = Get-SPClaimProvider | where {$_.DisplayName -eq "Provider DisplayName"}
    $mgr = Get-SPClaimProviderManager
    $mgr.ClaimProviders.Remove($prov)
    $mgr.Update()

  • After IOS6 upgrade game centre says my nick name already in use. has reset some games back to beginning, how do i fix

    After IOS6 upgrade game centre says my nick name already in use. has reset some games back to beginning, how do i fix

    I've had almost every issue you've had.  Finally on Friday the screen blacked out.  It was obviously still charged, since I could hear the message ring, but when I tried to light up the display it didn't light so I was unable to get to it unless I removed the battery.  Then, as soon as the display timed out, I couldn't get it lit up again without removing battery.  I had the same slow movements throughout the display as well as slow text messaging.  Every issue you had other than the alarm clock (that always worked well).
    I took it in yesterday and, after over an hour spent there with a 'professional', I still had no answers.  He told me to come home and copy everything from my sd card to my computer, then re-format my card.  Well, my phone didn't even recognize that I had an sd card installed!!  Nor did my computer! 
    So then I got to experimenting...I removed the card and viola!!!!!!  The phone worked GREAT!  It's never worked so fast!  I then installed my husbands sd card to see if it was my phone's card reader or my card.  Turns out that the phone still worked great with his card installed and it did recognize his card in my phone.  So, my conclusion is that I need a new card.  I couldn't believe the difference in speed of everything!  It's like a brand new phone! 
    As for the hard reset...I did that over the weekend, before I could get to a verizon store.  It didn't work at all.
    I'd say, do the same thing I did and see if that works.  Can't hurt!!!  Please keep me posted.  I'd like to see what you find out 
    Good Luck!!!!

  • Computers local host name is already in use

    I keep getting a message that states "This Computers local hostname [my i-mac name] is already in use on this network.
    The name has been changed to [my i-mac name-2].
    This happens a lot and I am now up to [my-imac name-88]
    Do I have the settings wrong?  Can anyone help me so that this doesnt continue. 
    I am not sure if someone is trying to gain access to my mac or not?
    Thanks

    Sometimes this message means that you have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. Disconnect the Ethernet cable or turn off Wi-Fi.
    Sometimes it happens because a device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.

  • Problem. Help please. Server Host Name "already used"

    Hello.
    This isn't very critical. But I'm getting a little tired.
    For some reason, from time to time, it appears the following message:
    "The server host name '[my nameXX]' is already being used. It has been substituted by [my_nameXX+1]".
    So it keeps incrementing by 1 that index next to the name of the computer...
    It seems like the name of the computer stays somehow in the net, in the router or in itself, and when I restart my MacBook, it finds that the name is already used.
    Any idea??
    Thanks in advance

    Hola ElPiter, y una cálida bienvenida a los foros!
    The last time I saw this I think it was the Router or Server doing it.
    Does everything have the latest Firmware updates? Routers in particulasr can't be trusted for any Auto update/notification of Firmware.

  • System tried to change local host name

    A screen message with an exclamation mark showed up on my Mac Mini screen this morning which says:  This computer's local hostname . . . is already in use on the network. The name has been changed to . . . (then inserted the current host name (# 2). I don't know what to make of this, and fear some kind of hacking. If this could be the case what can I do to find out?  The only other thing I can think of is that I left my Time Machine on & it tried to do a full backup with my backup drive full.  Anyone else have this happen?

    There are several possible causes for this behavior.
    1. Two (or more) computers on the local network have the same Bonjour name, such as "X's-MacBook-Pro.local".
    2. You have two simultaneous connections to the same local network: probably Ethernet and Wi-Fi. If applicable, disconnect the Ethernet cable or turn off Wi-Fi.
    3. A Mac wakes from sleep due to network traffic. This is a bug in OS X that may only affect some models.
    4. A device that gets its network address from the router wakes from sleep, and the address it was using before has been assigned to another device.
    5. A third-party wireless router has incompatible settings or firmware. In that case, refer to the manufacturer or ISP for support. Restarting the router may help, temporarily.

  • Cannot Update App-V 5.0 SP3 DB Server 'the specified name already in use'

    We planned to update our App-V  server from App-V 5.0 SP1 to App-V 5.0 SP3
    2 Servers (Both are Management Servers and Publishing Servers) with a remote SQL (2008 R2)
    we verified that all the registry keys exists according to the the
    Technet Document
    when we ran the setup file on the server we chose to install all of the roles and we got to the error:
    the specified name is already in use. you must provide a unique name database name
    The DB is already exist! we just want to update it to SP3 as well...
    So we installed all the roles but Management Server DB and the installation completed successfully,
    but now we still have a problem as the server can't connect to the DB (probably because it hasn't been updated)
    now we get this error:
    there were problems interacting with the database on the server. The error was: Invalid culomn name 'PackageOptional'.
    Invalid culomn name 'VersionOptional'
    we ran the setup with a domain admin that has full admin priviledges either on the App-V Servers and the SQL.
    we can't run the setup.exe on the SQL Server itself as it hosts many other DBs and doesn't have .Net Framework 4.5.1... besides the fact the DBAs don't really want to do it.
    we tried to backup the DB, attach it on a local SQL (under the App-V Server) , changed the registry keys to direct to the local DB and we got the same errors when we tried to run the upgrade!
    how come the documentation doesn't have anything about updating the DB?
    another question I couldn't figure out. can I use App-V Server 5.0 SP3 with App-V Client 5.0 SP2 HF4?
    anyway - please help!
    thanks!!
    Tamir Levy

    One more thing, I know how to expand the DB Scripts and run them manually on the SQL Server,
    but from my understanding, it is only to create new DBs and not to update the DB Tables...
    anyhow, I don't think the DB update should be such a complex and unfriendly method, especially when I took the DB and put it on a local SQL! this should be updated with a simple "Next , Next" Setup...
    Thanks
    Tamir Levy
    At the current time, there is some contradictory information available on technet.  On one side, the Planning for High Availability document describes how
    to extract the database scripts and run them against a SQL host so you don't have to run the EXE directly on the SQL host (yes, this does upgrade the tables too, not just create new ones, apparently the order to execute them is wrong).  On the other side,
    the App-V 5.0 SP3 Support Configurations indicates that any installation where you do not run the EXE on the SQL server is unsupported.
    As an enterprise customer who has SQL in a failover cluster, this confuses me.  I cannot run the installer on the SQL server (like you, and many other enterprise customers).  And even if I could, it doesn't mean the database would exist on the
    SQL server that it was run against, as the database can failover and nodes could be rebuilt!
    In regards to versions, when I said SP2 it was actually SP1.  You are correct, there were no server upgrades for SP2.
    Please be aware, I did not get the instructions to edit the database from Microsoft.  I provided them the steps I performed to get the application to work and I'm sharing them.  I am still waiting to hear back from them to see if this will be a
    supported path or not.  The setup was written to be executed directly on the SQL box, which is an unrealistic expectation for enterprise customers.  Even previous versions had to be extracted and applied via SQL scripts!
    The command above, from Alan, is part of the database scripts.  If you extract the scripts using /layout and /layoutdir (as described in Planning for High Availability),
    you will see a script called UpdateTables.sql.  This is a part of the script, not the whole thing.  There is more logic in this script that is required to get your publishing server up and running:
    It deletes all the daat from SchemaVersion then inserts a value of 2 into it.  If this doesn't happen, you'll get weird errors when trying to receive publishing information.
    If you can wait a few days for the upgrade, I would recommend that.  I expect some more documentation from Microsoft to come out and clear some of this up.

  • This computers local hostname is already in use?

    I turned on my computer this afternoon and was met with this message:
    "This computer's local hostname "Name of my hard drive.local" is already in use on this network.  The name has been changed to "The name of my hard drive-2.local"
    To change the local hostname, open System Preferences and click Sharing, then click "Edit" and type the name in the Local Hostname field."
    Can anyone tell me why is this happening?  I've never seen this before.  Has my computer been compromised?
    Thanks

    Sorry--I missed that first time around. I think you would do better by reposting in the Forum for  OS10.5. You have a software issue and that forum will have more software gurus. Machine-specific forums are better for hardware issues, but I think your hardwre is probably fine.
    If you wish, I can ask the Hosts to move this for you so you need not do anything. Let me know.
