Name of computer keeps changing to My ***** (2)

I have changed the name of my computer 8 times today in settings/sharing to remove the (2) after the computer name. The last time I changed it and before I could do anything the name changed! After putting the name back, the computer will again show up in the shared computer area of the finder
There are some apps that won't sync unless the computer name is correct.
What is causing the computer name to keep changing? It used to happen occasionally, this many times times in one day is absurd! It just changed again while I was typing this question.

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". Resolve the name conflict by renaming one or more of them in the Sharing preference pane.
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. You can avoid it as follows:
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
          Wake for Wi-Fi network access
if it's checked.
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.
6. If the router is an Apple device, it may need to be restarted.
7. A third-party Bonjour device on the network is malfunctioning. Finding out which is a process of elimination.
8. There is more than one DHCP server on the network. Typically, there would be two or more wireless access points configured to act as routers.
9. See this support article.
10. Back up all data. Make notes of your settings in the Network preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
          Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
Restart the computer and empty the Trash. You will need to recreate the network settings.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

MacBook Computer Name Keeps Changing

Recently my Mac computer name keeps changing. It's the normal name, but with a number at the end that keeps incrementing. How can I stop this?
I'm not sure if it's something to do with the fact I had a partition for the public OS X Yosemite, which I have now deleted.
Any ideas? Thanks.

I was having the same problem for awhile, even contacted support so they could screen share and see what I meant.
What I ended up doing was correcting the name and then unchecking all the boxes in Sharing. Open up Airport Utility and reset the router (basically I changed my password only because that's the easiest way to make it update). Go back into Sharing and recheck the sharing options that you had previously. Viola!
So far it's been a week now and my computer name has not changed. Hope this helps

Computer Name Keeps Changing

In the system preferences sharing where you go to set "Computer name" I am noticing that mine says "iMac (3)" I have changed it back but keeps renaming the name "iMac (1),iMac (2), iMac (3) and so on,,, ". My network hasn't changed, haven't added or removed anything. This Only happens when System goes to sleep. Any Help on this???

I had the same problem. I solved it. I use an Apple Airport Extreme. I had connected my computer to the Airport Extreme using an ethernet cable and I also activated WiFi on my computer. My computer kept changing names. To correct this i deactivated WiFi on my computer, connecting to the internet only through the ethernet cable attached to the Airport Extreme. No more name changing.

Why does the local network and computer name keep changing?

After upgrading to Yosemit the local network name and computername on my iMAC keep changes link:
Mycomputer-1
Mycomputer-2
Mycomputer-3
Why?
I have tried to change it back in sharing and network locations.
Is this also the reason the my iPhone cannot find my iPhone often cannot find my iMac when I will sync it? Then I have to restart the iPhone and iTunes on the computer. This happens very very often.
Maybe it also linked to these errors which the log is full of - many every minute:

I think the is some bug/clash between bonjour and other network protocols. That is only a guess.

After resetting the computer name and local host name to the correct name without the number I also shotdown my iMac, my AppleTV, my iPhone, my iPad and then rebooted my Airport/Time capsule it seemed to work at least for several days. But yesterday I discovered that my Apple TV now also has changed name to Apple TV (2).
I logged into iCloud.com to see my devices and here it was really wired. My Apple TV was called Apple TV (2) and my iMac also had (2) after the name. Then I checked it on the iMac but here it was correct! Why can it have one name on the iCloud and another on the computer.
I restarted both the iMac, Apple TV and Airport Time capsule then everything was correct also on iCloud.com.
But today the iMac was called the name (2) again on the iMac. And now the local host name also had -2 after the name. It has not always been both names that has changed. That is really wired. And today Wifi was not working on the iMac after wake from sleep. I changed the name back and rebooted again also the Airport Time capsule. Now it is working again.
The log is still full of this messages:

The name is not the only problem. Often itunes will not find my iPhone and iPad. Then i need to close iTunes and restart the iPhone and iPad then it works for some time.
And the iPhone and AppleTV will not always wake the iMac from sleep. I am wondering if the is linked to the changing of name.
I have seen by googling that it can be related to a sleep proxy problem so it seems like that here is two devices on the net with the same name that is why name is changing, but to know this do not help me to solve the problem. I have also seen all the suggestion to turn almost every services off on the computer, but again I it is not a solution and I have the iMac and devises to use the functionality not to shot everything down. So I do not really understand people saying turn off itunes, turn off blueboth, and turn off this and that.
Apple must soon come with a real solution. We are really many people have these problem since we upgraded to Yosemite and iOS 8.
I have also listed some of the iTunes errors from the log below:

Network share name keeps changing

I have setup my eMac to have the network share name eMac but it keeps changing into +eMac (2)+ does anyone know why?

well I do, but a short while later.
or some weeks or even month later, I can do it again.
this is a problem because I need to connect to it from my server.
the server is a Dell PowerEdge 1650 (I know, old, but it was cheap and it does the trick) which is running Linux Ubuntu Server 9.10 "Karmic Koala", since it's a server I did not install a DE(desktop environment) so I need to use the bash or shell (depending on what I do, since it has both)
how I connect it like this (on the sever):
+mount -t nfs "emac.local:/dev/macintosh HD" /storage/nfs/emac/+
the problem here: I use a DHCP, with DHCP reservation.
since I use DHCP reservation the IP should not change.
but the DHCP reservation doesn't really work correctly,
because of this, if my mac is offline (A.K.A off, I never disconnect it), the IP is in the pool, and thus can be assigned to a other computer.
since the IP may change depending on if it is on at a given time.
I need a way to always successfully identify my emac.
for this I use the network name.
and now it changes too!
which means that in order to find it I need to know if it still has the same network name, or what it's IP is.
I can find the IP from a web browser since it's my router who is my DHCP.
but the server doesn't have one.
so I'd have to use a other computer, since the router doesn't allow SSH/TELNET connections.

Ok, if reinstalling iTunes as suggested above does not resolve the issue of iTunes recognising the iPad then try this -
Firstly, make sure that your device is not hidden (left hand pane). If it just reads device then toggle between SHOW and HIDE.
Secondly, try all the other ports on your computer, even a number of times.
Thirdly, make sure your lead /connections are no faulty.
Fourthly, if you have another computer try plugging your device into it without taking any action, give it a moment, remove it and try it back in your other computer again.
Failing all that, see here - http://support.apple.com/kb/TS1538
And failing all that put the device into Recovery mode. See here and note the paragraph 'If you restore from a different computer.... ' down near the bottom of the page -
http://www.apple.com/support/ipad/assistant/itunes/
As for making your new laptop your 'home computer' follow these instructions -
1. Without connecting your iPad to your computer -
A) Install iTunes / make sure the latest version of iTunes is installed.
B) Go to the Store tab and click on "Authorise This Computer".
C) Go to Edit, click on Preferences [iTunes and Preferences on Macs] and click on Devices. Put a check mark in the box next to "Prevent iPods/iPhones/iPads from syncing automatically". Click OK and close iTunes.
2. Connect your iPad to your computer -
A) Start iTunes (it will not start automatically because of the action at 1(C) above).
B) Right click on your iPad under Devices in the left column. Select "Transfer purchases".
C) When the transfer has completed, right click on your iPad again and select "Backup".
D) When the backup has completed, left click on your iPad, click on the Apps tab, and put a check mark in the box next to "Sync Apps", and then click on "Apply" (bottom right).
E) Unless you want to always do a manual sync (as I do), go back to Edit, Preferences [iTunes and Preferences on Macs] and uncheck the box next to "Prevent your iPod.....".
F) Finally, on your iPad, check that everything is syncing properly. If not, go back to iTunes and check all settings.
NB You should not lose any apps. However, any 'purchased' missing apps can be downloaded again FOC. As with updates, this must be done with the Apple ID under which they were originally 'purchased'.

USB wireless adapter - interface name keeps changing

I have used different usb wireless (G) adapters with my 12" Powerbook G4.
Each was automatically assigned an interface name (BSD) such as en2, en4.
I recently updated to a Wireless N dongle (D-Link DWA140) which works great with my new Belkin Wireless N router.
I have had a few connection problems where the dongle was named as enNull.
After rebooting and re-entering the ip address via DHCP, I noticed that the same dongle has been renamed each time e.g First as en5 then en6, 7 and 8. It's now called en10
It works fine but is it possible to reset the name/number of this wireless adaptor using something like ifconfig in the shell Or some other way. I understand that en0 is built-in ethernet and en1 is Airport. I have 2 other dongles which are still identified as en 2 and en4. But my current dongle has an inflation problem and I would like to reset it if possible to a lower number.
Is this possible or am I mad to even consider it?
any help welcome.

That is very strange that PCI cards would keep changing names between reboots. Maybe you should investigate that to figure out what's going on. Check the dmesg and journalctl after each reboot and see what the interface is named as. Maybe that will give you some clues as to what "external" program is responsible in naming the interfaces.

Sequence and clip name keeps changing... Why ? Solutions ?

The sequence and clip name on a particular project keeps changing. It usually takes the name of of an audio file. Deleting the preferences, opening the timeline in a new project, making it offline and reconnecting it again, et. all doesn't help ? What is causing this ? HELP
Mac Pro Quad core
Memory 8GB
Storage - XSAN
FCP version 7.0
OS X version 10.5.8
Quicktime 10 & 7.66 both installed
Anyone has a solution for this....
Jp

I made the sequence off line and save it as a new project. Then deleted the preferences and opened the project..... reconnected the media. Most of the clips showed the correct clip name and the sequence name also didn't change. But a few audio tracks still had the old problem....
Thanks for the reply.... haven't updated yet..

[SOLVED] Network interface name keeps changing

My network interface name keeps changing between wlp2s0 and wlan0. This is a real pain, since I never know what name will be generated at boot. Most of the time it's called wlp2s0, so this is what netctl is set up to handle by itself. At boots were wlan0 is generated I have to connect manually.
I've tried making the name static by adding a rule to the /etc/udev/rules.d/10-network.rules. The rule i added was:
SUBSYSTEM=="net", ACTION=="add", ATTR{address}=="48:5d:60:7e:64:e9", NAME="wlp2s0"
Wlp2s0 is generated at boot alright, but I still have to connect manually with this solution. As if the "new" wlp2s0 is not recognized as the old one (same MAC). What gives?
This is on an Asus Eee 1001PXD, with the Qualcomm Atheros AR9285.

I've now been able to replicate the issue, and run the command:
journalctl -b
I did find the output:
mai 18 02:30:02 <hostname> systemd-udevd[126]: error changing net interface name wlan0 to wlp2s0: Device or resource busy
I haven't been able to process the whole output yet (I'll continue tomorrow if necessary), but I've found some things that I hope will clearify things. I get similar outputs to the following a lot throughout:
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: carrier lost
mai 18 02:30:03 <hostname> dhcpcd[237]: wlan0: waiting for carrier

mai 18 02:30:04 <hostname> systemd[1]: Starting Network.
mai 18 02:30:04 <hostname> systemd[1]: Reached target Network.
EDIT:
I see now that this is later in time, so that's not so strange after all. I'll look some more.
EDIT2:
The error code that a name change i impossible is the first time the term 'wlan0' occurs in the log. However there's a line much earlier that talks about wlp2s0:
mai 18 02:29:59 <hostname> systemd[1]: Expecting device sys-subsystem-net-devices-wlp2s0.device...
But as I said, if this information doesn't help, I'll have a closer look at the output tomorrow. Getting late here in Norway now.

Group names keep changing ..

I am creating a report will mulitple queries ..
i notice that the report builder keeps changing the
group name ..
a) how does report assign gruop name and
how can i change in a way report doesnt alter it ..
deepa

Hi Deepa,
Reports Builder will assign a default name to a group inside the data model when you write the query, but once a name has been assigned to a group, it should not keep changing the group's name.
For your own custom name, double click on the group heading in the data model, and type your desired name in the "Name" field of the Property Inspector that comes up. It should not change thereafter.

My computer keeps connecting to a server in the Netherlands instead of Singapore (where I am now).
What server? If it's based there, then that's the best that can happen.
In other words, I think you need to tell more on what you're trying to do or achieve, and what the problem is or the symptoms you're seeing.

TS3171 IO'S and bus names keep changing from session to session

My IO'S keep changing there names back to original factory names after I change names on bus and input output they do not save from session to session .i am in 9.21 ver and using lion any help would be great

To recap (correct me if I'm wrong), two things have to happen for session sharing to work: 1. the session must be passed in a cookie (the same cookie used by appls sharing the session), and 2. the appls must use the same authentication.One solution is for both/all participating applications to use an authentication scheme based on our built-in session management mechanisms that use a cookie in conjunction with our internal sessions table. The schemes may differ in most other repects, e.g., one might use LDAP and the other your own user tables to authenticate. N.B., the no-authentication (DATABASE) scheme does not use a cookie. Another solution is for you to implement your own session management infrastructure. With that, the only constraint on session sharing between applications is that a) the applications must belong to the same workspace, and b) sessions already "registered" in the internal sessions table with an authenticated username may not be used by a different authenticated user.
Optionally, if you want either of the appls to have public access you make the pages public.Yes.

Device Names Keep Changing

Hey all here is the problem I'm getting I set up all my devices and name them all for examples
Tom's Cell
Wendy's PC
Tom's PC
Jake's XBox
and the next time I go and log onto site it comes up as
Wendy's PC
Jake's XBox
Wendy's PC
Wendy's PC
it keeps changing names to Wendy's PC and I don't know why this is happening

Hi,
Are you seeing multiple IP addresses and Mac addresses for a device listed in the device list? You can apply the following steps to fix the issue:
Step 1: turn off each device
Step 2: go to the device list and delete the device that is showing the multiple ip address
Step 3: turn on each of the devices one by one and once it's showing in the device with a single ip address, add the device in the DHCP reservation list.
