When using the IPCONFIG -ALL command I have 52 Tunnel adapter local are connections "Media state: Media disconnected" listed.How can I delte them?Thanks in advance!Edith

Hi Edith, Thank you for posting. The tunnel adapters, please refer to the following: Tunneling protocol http://en.wikipedia.org/wiki/Tunneling_protocol Please Note: Since the website is not hosted by Microsoft, the link may change without notice. Microsoft does not guarantee the accuracy of this information. At this time, please try the following steps and see how it works: 1. Click Start, type cmd in the Start Search box, right click the cmd.exe, and then click Run as Administrator. 2. In the Command Prompt, type netsh int isa set state disabled, and press Enter. Meanwhile, I will also share the following documents with you: IPv6 for Microsoft Windows: Frequently Asked Questions http://www.microsoft.com/technet/network/ipv6/ipv6faq.mspx If the issue persists, please run ipconfig /all and post the report to the thread for our further research. Hope it helps. Nicholas Li - MSFT

Those are IPv6 tunnel interfaces, you can disable IPv6 if not using it. Hope this helps..

Hi Nicholas,sorry for my late reply, but the netsh command you suggested is most probably disabling IPv6 (and IPv6 multicasts?) , but does not solve my problem, that IPCONFIG -ALL shows now 57 "Tunnel adapter Local Area Connections*(s)1) Ido not want them, because they "overflow" the cmd-buffer not allowing me to see the essential IP Configuration2) they are useless to showand I just want to seemy IPCONFIG -ALL configuration as in legacy Windows.Any solutions???Thanksedith hochreiter

Hi Edith, Thank you for your update. May I know if you use the tunnel connection applications, such as VPN? If not, I can try to help your remove the adapters. At this time, please collect the following information for my further research: 1. Click Start, type devmgmt.msc in the search bar and press Enter. This would open up the Device manager for you. 2. Click View and select "Show hidden devices". 3. Now expand the Network Adapters section and take a screenshot of this. Meanwhile, please also capture a screenshot on the ipconfig /all report or copy the results to the thread. Capture a screenshot ============== 1) Press the Print Screen key (PrtScn) on your keyboard. 2) Click the "Start" menu, type "mspaint" in the Search Bar and Press Enter. 3) In the Paint program, click the "Edit" menu, click "Paste", click the "File" menu, and click "Save". 4) The "Save As" dialogue box will appear. Type a file name in the "File name:" box, for example: "screenshot". 5) Make sure "JPEG (*.JPG;*.JPEG;*.JPE;*.JFIF)" is selected in the "Save as type" box, click Desktop on the left pane and then click "Save". Please use Windows Live SkyDrive (http://www.skydrive.live.com/) to upload the files and share the URLs with me. Thanks you for your efforts. Nicholas Li - MSFT

Hi Nicholas,I understood that I am using a "VPN connection"wheneverI connect to the "public internet" from my private PC (with Vista Eenterprise installed at present)using any DSL line .... It seems that each time I connected from whatever place (Airports, Hotels, and even same private networks) Vista Enterprise added a "Tunnel Adapter Local area connection* #" (where as "#" means a subsequent number, at present resultung at 56!!!)I am trying to paste a screenshot "FROM WORD2 now:(Since I do not see any results of my screenshot paste "FROM WORD" - I hope this is only "by design" :-)Edith

Hi Nicholas,I uploaded the screenshots of IPconfig -all and Devmgr.URL:https://cid-b32be0a082acb71c.skydrive.live.com/self.aspx/RemoveTunnelAdapterInVistaAccess permision set to Nicholas Li.Many thanks for your helpEdith

Hi Edith, Thank you for your response. I am sorry that I cannot access the file you shared. This may bedue to the permission settings on the file. To be simpler, please just share this without setting the permissions and give me the URL. I will try to access it again. Once I get the file, I will perform some further researches on this. Thanks. Nicholas Li - MSFT

Hi Nicholas,it is now shared for Everyone at this link:URL:https://cid-b32be0a082acb71c.skydrive.live.com/self.aspx/RemoveTunnelAdapterInVistaThank you.Edith

HiEdith, Thank you for update. After checking the screenshot, I found some tunnel adapters are the same (for example, the ISATAP {44696E8D-B02D-44BE-A326-C649D77F0A0A}). At this time, please remove the duplicated ISATAPdevices manually and see if it works. Note: Please perform a full system backup before doing this. Hope this helps. Thanks.Nicholas Li - MSFT

Hi Nicholas,I deleted ALL ISATAP devices in Device manager and it helped partly, because I still have "Tunnel Adapter Local Area Connection" #12, #36 and #43 listed in IPCONFIG -ALL, but at least I can see the essential IP configuration, without scrolling back forever.How comesthese huge amount of"Tunnel Adapter Local Area Connection" are created and how to avoid this???Thanks and nice weekendEdith

Hi, Thank you for your update. I know that there are still some Tunnel Adapters exists. At this time, please post the Ipconfig /all report to the thread again and we will continue performing some further researches. If you dont use IPv6, you can try to disable IPv6 and check the results. Disable IPv6 ======== 1) Go to Control Panel - Network Connections. 2) Right-Click on the connection and click Properties. 3) Uncheck the Internet Protocol (TCP/IP) Version 6 in the list and click OK. 4) Please reboot the computer to see if it works. Hope this helps.

Nicholas, I just want to say this information was very helpful and help to solve my 37 tunnel adapters. Thanks.

Yeah I had the same problem and it drove me insane! I think that it has to do something with using different networks all day long. The steps I took to resolve this was: 1. Opened up network connections and disable IPv6 2. Opened up device manager (start > type "devmgmt.msc") - View > Show Hidden Devices - went under network adapters and deleted all the ones called Microsoft 6to4 adapter That took care of the problem for me. Good luck! BTW I am using windows 7 Ultimate on an HP G62 laptop

Hi all, I have the same issue at my windows 7 laptop. It has created 290 (!!) network adapters and caused my laptop to become rather slow after startup (ip helper service using a lot of cpu at start up). I did all that was suggested except that I can't really manually delete all adapters. When I delete one my computer freezes up for about two minutes, meaning deleting them all would take over 10 hours.. and I have better things to do than that :P I posted a screenshot in my public skydrive folder (see link below). But as there are so many adapters I cannot get them all in one screenshot.. Is it by design that a new tunnel adapter is created every time I connect to a new network?? If I would get anymore I'm afraid my laptop would become pretty much unusable the first five minutes after startup (it appears to be checking all adapters), also my laptop is a recent core 2 duo, I use windows 7 ultimate upgraded from windows vista. http://cid-ca9eb97990e938be.photos.live.com/self.aspx/Public/network%20adapters.jpg http://cid-ca9eb97990e938be.photos.live.com/self.aspx/Public/tunnel%20adapters2.jpg If anyone would know an automated way (scripted, or in c#) to delete them I would be very grateful! Thanks, Tom

this helped me so much. found this while I was searching the internet for hours looking for a solution never ran into a problem like this before (it had to do with vpn software). thanks

Hi Nicholas, I watching my posts from time to time and I AM SURPRISED that as of today (Sept. 6, 2010) ONLY over 20,000 (frustrated?) users have had the same issue. Now, I would like to know the technical explanation on how to prevent this issue! I am expecting something like: "update your system using Windows Update ....." Many thanks Edith

Hello all I also have this problem, if it is affecting performance on startup or elsewhere then it is quite serious. It happens so easily and is not obviously a performance related issue - but ultimately makes Windows 7 performance look poor. Thanks Ivan

Found it! It was driving me nuts. Even after I disabled Tunneling, ISATAP and IPv6 they were still there. Go to> Control Panel > System > Device Manager > View > Show Hidden Devices > Network adapter> There they are! Delete them there and they are finally gone in the ipconfig.

If you are just trying to get your current IP address (off one of the first adaptors listed), you could just type "IPCONFIG |MORE". This causes the list of adaptors to come one page at a time (you have to hit a key to go to the next page). You can then read the IP address off one of the first ones listed. Mark this reply as "answer" if you think it helped you. Thanks!

I disabled V6 and still had a machine talkign to me via a 2002 v6 6to4 address. Does this mean that v6 is being routed? JasonJason Yates

I have found this problem on my Windows 7 machine. I get tunneling on connections 8-447. This might explain why I am having slow startup and can't connect to the internet until I have been up for 7-10 minutes after startup or startover. How do I know if I need IPv6 address or not? I hate to disable something when I don't know what it is doing. Also, I can hide these 'Media disconnected' notices but will they still be taking up computer time afte Ipv6 is disabled or will it still be using resources?

I am having the problem and am showing over 400 entries from 8-447. I entered the netsh comand and it accepted it but the 'ipconfig' message still goes through the entire set of adapters. I also disabled it in the network. How can I get rid of the existing entries?

I have disabled IPv6 as suggested and that has speeded up my ability to get on the internet quicker. I have also found that I cannot set up a Homegroup Network with it disabled. There is something basicly wrong with my computer setup for Windows 7. Over 400 of these messages is WRONG and I can't set things right. Each of the 400 entries is as follows, with only the number at the end of the first line changed. They start at around 30 and go up to 437" Tunnel adapter Local Area Connection* 406 Media State . . . . . . . . . . . . . . . . . .: Media disconnected Connection - Specific DNS suffix . . .: This repeats over 400 times and before I disabled Ipv6, it would take 5-10 minutes after startup or startover before I could get to the internet. I found the problem while trying to set up a home network between this Windows 7 computer and a Windows Vista computer. I can't set up the Homegroup option because it requires Ipv6 be enabled. I would appreciate any help you can give. I am an old fart and am slower to resolve problems than I was a few years ago.

I went into device manager and disabled the 6to4 adapter and that cleared up my ipv6 issue. You have to unhide the adapter (View >show hidden devices). I'm with you, I don't understand v6 well enough but this seemed to help. I haven't tried this, but you might be able to run IPv6 with the 6to4 & tunnel adapters disabled. Then again, HomeGroups might require these adapters. My understanding is these adapters aid in the transition between ipv4 & ipv6 and are used in many networks moving to ipv6.Jason Yates

Please refer to this page to automate removal http://ryanvictory.com/posts/automating-6to4-adapter-removal-in-windows/ Note: If u r using Windows 7 follow the link below to download the latest version of "devcon" instead of the link given in above page, step 3, article 1. http://download.microsoft.com/download/4/A/2/4A25C7D5-EFBE-4182-B6A9-AE6850409A78/GRMWDK_EN_7600_1.ISO The iso file is around 620 mb, and u need to extract your version (x86 / x64) of devcon from this file as explained here: http://www.techlikes.com/2010/09/devcon-problem-in-windows-7-solved.html#

My problem has been fixed. I have disabled IPv6 and uninstalled all 447 of the Tunnel Adapters that the ipconfig listed. I displayed them in device manager with ;show hidden files' and individually uninstalled each one. My Network works fine now. I have no problems. I am a little worried about disabling Ipv6 because I feel that it will be required in the future. I am convinced that it is a Windows 7 problem though and MS is bound to fix it sooner or later. There are too many people having a problem with it for them to just ignore it. Thanks for all comments.dond13

if someone wants to Remove all 6 to 4 adapter automatically can use That: http://www.sordum.com/deneme/6to4/download.php?Down=6to4remover.zip

The removal program worked for me! Thanks !!!

Man, I've been looking for a solution to this for THREE YEARS!!! TWO THUMBS UP!!!

if someone wants to Remove all 6 to 4 adapter automatically can use That: http://www.sordum.com/deneme/6to4/download.php?Down=6to4remover.zip Thank you. Thank you. Thank you. At the moment, I'm removing 600+ 6to4 adapters.

I thought I had a record of 447 adapters. I did it without the tool though and it took forever - one at a time.dond13

Looking into the commands of this, please note it does disable tcp ipv6

Note that the version of devcon.exe included in the package above does not work on Windows7 64bit. It will execute but it can't remove the devices. I found the solution for this in comment #20 on this blog: http://ryanvictory.com/showpost.aspx?title=automating-6to4-adapter-removal-in-windows/ If i may quote: "If anyone's interested, the windows driver kit (http://www.microsoft.com/downloads/en/details.aspx?FamilyID=36a2630f-5d56-43b5-b996-7633f2ec14ff&displaylang=en) contains a version of devcon that works fine on 64 bit windows." It's located in this cab, to be exact: \WDK\setuptools_x64fre_cab001.cab Just extract _devcon.exe_00000 with windows explorer and rename to devcon.exe

I do not understand, I downloaded the devcon.exe from the link you provided but it still doesn't work?RGill

This works for me and I got Windows 7 Pro x64: How to disable certain Internet Protocol version 6 (IPv6) components in Windows Vista, Windows 7 and Windows Server 2008

thanks man for the solution given appreciated.

Thank you so much! This method worked really well for me. Like previously metioned, this problem caused my PC to start up much slower. Now my Pc literaly starts up 4 or 5 times faster. For everyones information, my Pc is running on "Windows 7 Home Premium 64 bits ".

if someone wants to Remove all 6 to 4 adapter automatically can use That: http://www.sordum.com/deneme/6to4/download.php?Down=6to4remover.zip I was hoping "wtarkan" could specify what his 6to4remover was doing, please? ryan's is a batch file, this is an executable. It uses devcon, (built into this executable?) to remove the tunneled connections, but it did additional steps at the end, including a registry modification. Knowing what it is doing would be more valuable for me, than clearing away all the 6to4 entries. Hope you don't mind providing the feedback. And, thanks!

just right click the i386.exe and extract :) 1. 6to4remover.bat 2. devcon.exe 3. tunel.reg what is tunel.reg : Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters] "DisabledComponents"=dword:ffffffff Disabling IPV6 All methods are part of the Microsoft`s Methode , I have just used them :)

Our University NOTEBOOKS running Win7 PRO 32-bit have had this problem randomly, so I have yet to pinpoint the CAUSE and why some identical notebooks get the "tunnel adapter" problem and others do not... Usually they call me in the IT dept. when it gets so bad that they no longer have access to network drives... How we remove these virtual tunnel adapters is run DEVCON with the following command line: devcon remove *6TO4MP This then removes all the adapters shown in IPCONFIG /ALL I am still searching for the reason WHY this is happening, and why only random machines, not ALL the Win7 notebooks... Anyone know yet? Robert

My understanding is this tunnel adapter 6to4 is automatically created depending of the IPv4 range. It looks like this 6to4 tunnel interface is not created on IPv4 range like : 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, and 169.254.0.0/16. One way to prevent 6to4 to be automatically created is to use the following command: netsh interface ipv6 6to4 set state disabled

Those are IPv6 tunnel interfaces, you can disable IPv6 if not using it. Hope this helps.. Worked for me. Thank you! --Harald-René Flasch (aka hfrmobile)Programming is a kind of art but not all programmers are artists.
