Unknown network name on my computer

I have in addition to the local network I created a few years back, suddenly an unknown network on my list, using my high speed internet connection? when I try to access it, it will ask for a password... I would like to know how I can delete this network and how I can prevent this from happening again. I use an ibook, latest tiger os, and a g4, os 10.3.9 Any suggestions? thanks, e_moma

e_moma, Welcome to the discussion area!
...suddenly an unknown network on my list...
That is a wireless network created by one of your neighbors.
I would like to know how I can delete this network and how I can prevent this from happening again.
You can't. Your Mac will show all available networks on the list. Kind of like hearing your neighbor's dog barking.

Change Computer Network Name

Hi all,
I'm trying to change the network name of my computer that windows pcs use to connect. Currently, to connect to my computer, I have to type "\\new-host.linksys\" in explorer to connect to my macbook. I've found where to change the "workgroup" that the computer connects to, but I can't seem to find where to change that new-host.linksys to something like macbook.
Any help would be appreciated.

I would suggest you download Bonjour for windows.
Then once installed you windows pc's can connect to your computer using its machine name.
if you goto your sharing preferences and give your mac a name such as macbook
then its bonjour name is macbook.local

Giving my phone a network name

My phone shows up on our wlan as unknown-3, all our other wlan connections show up with their names. How do I give my N97 a name that will display on the wlan?

If you go to System Preferences -> Sharing, what do you have listed as the "Computer Name:". I believe that should be the network name of the computer. HTH.

How can I uniquely identify computers on the same network/account specifically for airdrop use? When I change name on one computer under contacts if changes on all computers.

How can I uniquely identify computers on the same network/account specifically for airdrop use? When I change name on one computer under contacts it changes on all computers. I would like to change icon and name for each computer.

you would need to setup a VPN and tunnel into your office.
FYI..the default ports are 3283 and 5900.

Computer name change and Network name

Recently I changed my computer name from "XY Z's Computer" to one without the dreaded apostrophe and the spaces.
I did this in Sharing under Computer Name:
However, after doing this and rebooting, the new name is there - good - but if in Sharing Preferences, I click Internet Sharing and then click Airport Options, my original name is there, under the title, Network name:
Is there a single location where these changes can be made simultaneously?
Are there any other places where one might find the original computer name?
Is this a bug or simply something not well-documented that I should have known about?

i'd like to know how to do this also

How to stop the computer from changing its local network name when waking up from sleep mode

How do I prevent a mac mini from changing its' network name automatically when it wakes up from sleep mode... It will wake up and display a warning that the network name is already in use and it changes its name to (n+1) name with number after it... I know that there is no other device with that name because the only other things on the network are 2 hard drives (one being used for time capsule) and a printer..
This is very annoying and needs to be fixed.... don't tell me to make the computer never sleep because that defeats the power savings settings under power management.

Go to System Preferences>Network>AirPort and delete your network from the Preferred Networks box. Reenter your network information. Make sure that AirPort is the topmost listed interface when you Show Port Configurations. Apply the changes and Restart. Does it work now?

The name of your computer "name(7)" is already in use on this network. The name has been changed to "name (10)".

I know why this happens - there are two network connections to the same network. One is wi-fi, the other is ethernet.
I can stop it happening by turning off wi-fi.
I'd rather keep both connections, though.
Is there a way of adjusting this so it stops doing it?
Should I be using the route command to set up different routes to the two links?
If so, what's the best way to do this?

I thought about it ...
The name of the computer have different meaning.
Normally, the computer name, or in this case 'hostname' refer to the RFC of DNS, Domain Name System IP Service, that resolving 'speaking names' to IP adresses. If your Computer is a Part of the global, Public Internet and so listed on a Public Domain Name Server, the function 'global hostnames' should bei used.
The local hostname refers to the apple Bonjour Service, to solve local network units. (http://support.apple.com/kb/ph3763)
The need of different interface names for your Computer sounds strange to me, because the name represent the same machine, the same services your computer offer in your Network.
I had similar symptoms in my network, because i Need to use both interfaces (ETH an WLAN). But, this problems were related to adress conflicts, refresh time of routing tables in my network. Since i use static IP adresses for my mac interfaces, all things ok and i never seen again any problems.

How to change computer network name?

We're swapping 2 computers in our office. How would I change their network names to represent their new user/location? As well as changing the computer's user account?
The way our current setup is that each room has a name, and the room name is the computer network name as well as the user account name.

you mean the computer name is like "iMac-24inch-at-room-1.local" when you browse the networks ?
If so, Just change it in System Preferences->Sharing.
or the wireless SSID, eg. Airport connected to "Room 1" ?
if this is the case, just select the new room BS and set that in Airport Pref network.

Network name reverts to "David Fahnestock's iMac" when I boot computer

My network name is "Cisco1962", but when I restart the computer, the name changes to "David Fahnestock's iMac".
I have to go back to Network each time to reset it.

Try the following, in order, until (hopefully) resolved:
1a. Delete Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Under "Preferred Networks," delete the network(s) you regularly use from the list.
1b. Delete AirPort Keychain Entries
Launch the "Keychain Access" application located in Applications/Utilties.
Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
1c. Add Preferred Network(s)
System Preferences > Network > AirPort > Advanced > AirPort tab
Add the preferred network(s) using the "+" button.
Restart or log out then back in.
2. Move System Configuration Files
(Note: You will have to reestablish your network connections settings.)
Go to /Library/Preferences
Move the SystemConfiguration folder to the desktop.
Restart your Mac. (Note: OS X will rebuild the files that are now sitting on your desktop. If this doesn't resolve the issue, you can move the folder back to it's original location.)

Error Message: " '[name of my computer]' did not respond. (error -8)

I know that this topic has been submitted a million times, but I need personal attention now. The topic discussions have been really helpful except for the fact that my ichat video STILL DOESN'T WORK. I read and do all the sets of advice and instructions and STILL NOTHING.
My main message usually always says, " '[name of my computer]' did not respond.' The only differing message I've received is from my mom's laptop (a Dell Latitude D610, Intel) which says that " '[name of her computer] has declined'. I've checked out the error reports which are always labeled (error -8).
Once I was able to connect, with absolutely no hitch, when I was sent an all out video conference chat from a G4 Mac about 4 months ago. My ichat hasn't worked since which is why I've been trouble shooting since then.
Based off of the advice, I opened ports 5060, 5190, 5220, 5222, 5297, 5298, 5353, 16384-16403 on both TCP and UPD and turned the firewalls off in one then turned them on again.
I've read the iChat support and they all say that they are compatible with tons of operating systems and platforms. But, my video still doesn't work to other computers or work in general. Please can someone tell me how to get this to work? Puhleeeease. I've been at it for months now....
Thanks!

I, too have had the same problem, but only recently — maybe coincident with recent updates to iChat — and I too would like to know what error -8 means.
I am running a Dual 1GHz PowerPC G4 Mac with automatically updated software, connected via ADSL at 512/128. The Internet Interface is a router/firewire/switch/modem (D-Link DSL-G604T) and I have programmed it to keep the required ports open. The audio input is from an iSight: audio out to some external speakers from line out. Programming hasn't been changed for months, and the problem has only occurred recently, so it doesn't look like a Firewall or address translation problem.
In my case, I tried several things:
1. I tried to initiate an audio chat with someone who has a Mac Mini PowerPC with most updates on it, and a 56K modem. I have had many audio chats over many months with this person.
Some days ago, it failed to complete a connection with the comment that my end didn't answer. I take this to mean that the final handshake message from the my end wasn't sent, since the connect window indicated the other side had responded positively.
The buddy on the other end then initiated an audio chat session to which I responded. This time, error -8 was accompanied with a message that the other side had failed to respond to the final handshake.
I presumed that it was some sort of glitch either on the network or in my computer and we finished the conversation on the phone. The system has been rebooted several times in the meantime, and the integrity of the system disk checked: that should have got rid of any local anomolous state
2. The exact same thing happened today when I attempted to communicate with a new buddy introduced through email. This new buddy has recent (but unknown to me) Mac equipment running OS X, and a broadband connection.
We were testing the connection after she had set up iChat with an AIM screen name to be ready for a Saturday sched to step her through installation of some difficult to set up software.
At that point, I realised my first failure wasn't a system glitch, and found this message board.
So, any help from anybody?
Keep in mind that this is a recently-introduced problem on a stable (other than Apple updates?) system that has been running on audio and even one-way video with 4 different buddies (three on Macs and one on Win XP with AIM) for months.

Failover Cluster Network Name Failed and Can't be Repaired

I have an issue that seem to be a different problem than any others have encountered.
I've scoured everything I can find and nothing has fixed my problem.
The problem starts with the common problem of the cluster network name failing on my 2 node server 2012 file server cluster. The computer object was still in AD and appeared to be fine so it was not the common problem of the object
getting deleted somehow. At the time, there was no other object with that name in the recycling bin, so I don't think it was mistakenly deleted and quickly recreated to cover any tracks, so to speak.
Following one guide, I tried to find the registry key that corresponded with the GUID of the object, but neither node in the cluster had it in its registry (which may be part of the problem).
Since it was in the failed state, I tried to do the repair on the object to no avail.
We run a "locked down" DC environment so all computer objects have to be pre-provisioned. They were all pre-provisioned successfully and successfully assigned during cluster creation. The cluster was running with no issues for a month
or so before this problem came up.
When I do a repair on the object while taking diagnostic logs the following 4609 error appears:
The action 'Repair' did not complete. - System.ApplicationException: An error occurred resetting the password for 'Cluster Name'. ---> System.ComponentModel.Win32Exception: Unknown error (0x80005000)
There appears to be a corresponding 4771 error with a failure code 0x18 that comes from the security log of the DC that states there was a Kerberos pre-authentication failure for the cluster network name object (Domain\Clustername$)
I believe this is what is causing the repair failure. All the information I found related to security error 4771 was either a bad credentials given for a user account or the fix was to reconnect the computer to the domain. I can't seem to find
a way to do this with the cluster network name. If there's a way please let me know.
I've tried a number of things, like resetting the object, disabling it, deleting and creating a new object with the same name, deleting that new object and recovering the original, etc...
Can anyone shed some light on what is going on and hopefully how to fix it other than rebuilding the cluster? I'm quite close to just tearing it down and building it back up but am hesitant because this cluster in currently in production...
Any help would be appreciated

Hi,
I don’t find out the similar issue with yours, base on my experience, the 4096 error
often caused by the CSV disk issue, and the 0x80005000 error some time caused by the repetitive computer object in OU. Please check the above related part or run the validate test then post the error information.
Although I do have a CSV, there doesn't seem to be any problems with it and it was running just fine for a month or so before the problem started. I double checked and there is no duplicate computer objects, maybe I don't understand what you mean by
repetitive, could you explain further?
The cluster validates successfully with a few warnings:
Validating cluster resource Name: DT-FileCluster.
This resource is marked with a state of 'Failed' instead of
'Online'. This failed state indicates that the resource had a problem either
coming online or had a failure while it was online. The event logs and cluster
logs may have information that is helpful in identifying the cause of the
failure.
- This is because the cluster name is in the failed state
Validating the service principal names for Name:
DT-FileCluster.
The network name Name: DT-FileCluster does not have a valid
value for the read-only property 'ObjectGUID'. To validate the service principal
name the read-only private property 'ObjectGuid' must have a valid value. To
correct this issue make sure that the network name has been brought online at
least once. If this does not correct this issue you will need to delete the
network name and re-create it.
- This is definitely related to the problem and the GUID probably got removed when we attempted a fix by resetting the object and trying the repair from the failover cluster manager.
The user running validate, does not have permissions to create
computer objects in the 'ad.unlv.edu' domain.
- This is correct, we run a restricted domain. I have a delegated OU that I can pre-provision accounts in. The account was pro-provisioned successfully and was at one point setup and working just fine.
There are no other errors nor warnings.

Windows Security Error! Logon failure: unknown user name or bad password

We RANDOMLY can't access one of the computers in our company's network. It is now saying - Windows Security - Logon failure: unknown user name or bad password. It doesn't matter what I put in for a user name and pw it still doesn't work.
Any help is much appreciated!

To be added, if it is part of domain, is this computer had local account? If so, try to logon local account for test, If sucessfully, follow Cyber's suggestion remove PC from domain and rejoin it for test.
If not, you can try to boot system into recovery mode and choose recovery computer for test.
Press F8 at startup, then choose Recovery system.

Windows 7 or Windows Server 2008 R2 domain join displays error "Changing the Primary Domain DNS name of this computer to "" failed...."

Hi,
Windows 7 or Windows Server 2008 R2 domain join displays error "Changing the Primary Domain DNS name of this computer to "" failed...."
DC:windows Server 2008 R2
Domain functional level:Windows Server 2003
When Winxp join domain, have no this error message.
I checked http://support.microsoft.com/kb/2018583?wa=wsignin1.0 does't work.
There have 3 suggestion in this article:
1.The "Disable NetBIOS over TCP/IP" checkbox has been disabled in the IPv4 properties of the computer being joined.
Doesnt's work.
2.Connectivity over UDP port 137 is blocked between client and the helper DC servicing the join operation in the target domain.
On my DC, I run netstat -an, reslut as below:
UDP 192.168.20.3:137 *:*
3.The TCP/IPv4 protocol has been disabled so that the client being joined or the DC in the destination domain targeted by the LDAP BIND is running TCP/IPv6 only.
We are not using IPV6.
This server recently updated from Windows Server 2003 to Windows Server 2008 R2. Before upgrade, when Win7 and Win2008 join this domain, also have the same error message.
Please help to check this issue.
Thank you very much.

Hi Guo Ying,
I have faced this critical error which makes over-writes the host names in the domain when you join.
For example: Already you had a host name called as PC.domain.com in the domain.com Domain.
When you try to add the another host name called as PC in the domain.com Domain, it doesn't give you the duplicate name error on the network it does over-write the existing host name called as PC.domain.com & it will add the new host name into the domain.
Host name which got over-written will get removed from the domain. I faced this issue in my project. My DPM host name got removed from the Domain & new host name got joined into the domain which halted my backups for one day.
Final Resolution is as follows:
You need to start the dns console on the DC & drop down the domain name.
Select the _msdcs when you click on _msdcs it will show the Name Server's list on the right hand side.
You need to add the Domain Naming Master under the _msdcs or add all the domain controllers which you had.
After you add the Name server's try joining the PC OR Laptop to the domain which is successfully joins it.

Safari of my Macbook (on WiFi) suddenly fails to connect to the Internet. A popup window message says another device on the network is using my computer's IP address.

But then there was still no Internet access even after I have disconnected all other home computers (a total of four including the Macbook and one iMac desktop. For simplicity, I shall categorically called them Mac hereafter unless otherwise specified. The Macs are operating on WiFi.).
The window message recommends changing the IP of either the Macs or the other device. The latter of course does not apply because I don't think the other device is one of my computers.
My questions:
(1) Why did that happen suddenly since the Mac and other computers on the WiFi was working fine in the morning (as well as days before) and then all of a sudden an unknown device is using my computer's IP? As far as I (we) can remember, we did not do any thing unusual this morning nor had we downloaded any special programs.
(2) How do I change the IP since it requires Internet acess to do it and since I can't access the Internet on the Mac?
(3) I am almost sure the problem is not caused by the Internet service because when I connected the Ethernet cable from the DSL modem to an old Windows PC, I got Internet via Internet Explorer. [I am actually sending out this message via IE on my PC.] However, when I cennected the Ethernet line from the modem to a WiFi router (Airport Extreme) and then connect the router and the old PC, I did not get Internet on either the Mac nor the PC. Similarly, there was no Internet on both Mac and PC If I connect Ethernet only between the modem and the router but not between PC and router. So, the question is whether a third unknown party has gotten hold of my Mac IP address and is trying to break into the Mac? Can it steal my personal info?
(4) How can I repair the Mac now and prevent future recurrences? Is changing the IP address the way to do it? (But like I said before I had tried but could not change the IP because I did not have Internet access on the Mac. Is there an alternative method?)
(5) I wonder if a computer's IP address remains constant if you don't change it. The reason I am asking this question is because the aforesaid window message on the Macbook--not sure about the iMac--shows a different IP address--a few numerical digits were changed--almost every time it pops up following every failure trial of mine to access the Internet. Was the Macbook trying to change the IP for me or was there some thing not right?

Re: Another device on the network is using your computer's IP address.
This message/problem was occuring intermittently for me in a household with two MacBooks accessing one Airport extreme. Rebooting the modem and router would only temporarily fix the issue for me, so I spoke with a friend who works for Apple and it seems that the Airport Extreme settings were at the root of our particular issue.
The router(Airport Extreme) recieves only one IP address from the modem and in order to allow it to share the IP address with two computers at once, the solution in my case was through:
Applications>Utilities>Airport Utility>Manual Setup>Internet
under Internet Connection- Select "share a public IP address"
under NAT, check the box for "enable NAT Port Mapping Protocol"
(this will allow the sharing of one public IP address with multiple devices)
if this is a new setting, then click "Update" and the Airport Extreme should reboot itself with new settings applied.
When all else is working properly, this is a satisfactory solution in my case.

64 The specified network name is no longer available

Hi Experts,
We have been using TMG 2010 from last 5 years as a reverse web proxy for OWA , outlook anywhere , active sync etc. Of late users from one particular site have been complaining of regular disconnections on outlook and OWA.
We don't have complaint from any other site except to this , whereas users in this site can browse other secure web sites without any challenge.
I have diagnosed the packets coming from their public IP and i could see that lot of connections happen successfully whereas few it shows either denied connection or failed connection attempt.
if i concentrate on failed connection attempt , i get the below information. Can some one provide any hint on the possible resolution for this issue.
Any help would be much appreciated

Hi,
>>64 The specified network name is no longer available
This error is very general. You need to collect a network trace and analyze it. The most common one is when the backend server is performing a dirty TCP connection reset.
You could have a look at the blog below.
Error 64 “ The specified network name is no longer available” while accessing a
