Specific PCs Infecting Networks They Join With IPV6
Aug 22, 2012
I have a set of PCs which if connected to a windows network will make all computers on that network default to ipv6 when resolving names. This happens even if IPv6 is unchecked, if the ipv4 binding is set above 6 in the advanced properties of the network card. If any of these PCs joins a network with a point of sale system (Aloha) that system develops problems since Aloha does not like IPv6. At all. All computers including the aloha terms are Windows 7, 32 or 64 bit. Reproduced this with different routers and network topologies.
For example, I take one of these particular PCs to my home network Prior to the terminal going onto the network
ping localhost --> 127.0.0.1
ping computername --> 192.x.x.x
After the PC has joined the network, just attached to the same router, not on the same workgroup, etc., now all computers on the network return
ping localhost --> ::1
ping computername --> 08fe:xxxx (IPv6 address)
ping computername -4 --> 192.x.x.x
ping localhost -4 --> 192.x.x.x
This behavior continues even without IPv6 enabled on any adapter on the network. When the PC is removed from the network, all other PCs continue with the new behavior. I have tried netsh winsock reset, net stop dnscache, netsh int ip reset.log hit, unchecking IPv6 in multiple places, ensuring binding order has IPv4 above IPv6 on all network adapters (none hidden) etc. It's like this PC infects other windows PCs with IPv6. I have not tried disabling IPv6 from the registry or by Policy in my lab but I believe I tried this on previous network with no effect.
I have a desktop that is connected to my Belkin router via wire. I have 3 laptops that are all connected to the router wirelessly. All computers have Windows 7 64bit and synched clocks. All are connected to a Home network. All 3 laptops detect that a Homegroup has been created on the wired desktop. I'm using the correct Homegroup password. All computers have discovery on. All computers have IPv4 and Ipv6 running. All services are running. Everything else I've read and tried regarding troubleshooting this issue haven't worked. All computers can see each other on the Network, but can't connect to the Homegroup.
I've looked absolutely everywhere I can think of and I can't find a way to disable auto-joining unknown networks. There has to be a way to do it, otherwise that would be a huge security flaw. When in range of my own router or any other access point I have saved, it's fine. However, When I take my laptop elsewhere, it automatically joins unprotected networks, which I don't want to happen
I was wondering if it was possible to have specific IP configurations for Wifi networks.For example, when I connect to network "wifi1" I get automatically DHCP address, and when I connect to "wifi2" I get static IP which I defined before.
I m trying to connect two PC using IPv6 and i m getting reply to connected but i can't access shared folder it say Network Error Windows can't access.i m tried following Address \fe80::1 So How can i get shared folder Using IPv6..
im getting this error im loged in my internet now but on IPV6 network settings it says ipv6 no network access can you help me .also troubleshoot it and it says "your computer does not meet the requirements for direct acess why also when im using internet the conection wents off sometime
I'll try my best to explain all the issues clearly.from very above downto the third line are:IPv4 connection : not connected (Not OK, it wasn't like that)IPv6 connection : not connected (No public IPv6 connection in China, this is OK)Media State: connectedBut as you can see below, network is OK (Yeah, it seems that). The problem is, this ADSL connection is not showed in 'Avtive Networks'.Most online activities are OK, but somw applications like EA Origin are malfunctioned(I'm sure it is because of the problem in network connection)I've tried reset my winsock, LSP, netsh int ipv4,also reinstalled drivers. All above didn'you may wanna have a look at my Network and Share Center. Here it comes.Area 1 shows that there is no active networks except a 'unidentified network'(this refers to Local Area Conncetion. Since I don't neither have a router nor use LAN, that don't matter). When ADSL was OK, I got a active ADSL network there.
IPv6 shows No Network Access. Never had this before. WOn't let me log on to my Diablo 2 Battlenet(Yes 2, not 3, yet) No idea why or how it happened. This is a desktop and hooked up by a wire.And now saying No Internet Access!
I have a QNAP NAS and several devices (mostly Windows 7 and iOS devices)The vast majority of my networking setup seems OK - however on one Windows 7 laptop I am having problems. The Laptop can 'see' remote shares, access the Internet and ping other devices on the network - however remote devices cannot ping the laptop. Whilst trying to ascertain what could be the cause I thought that I would ping 'localhost' on the laptop - after all, it should be able to see itself!
My wifi was working fine a few days ago but i think the windows update has messed up my wifi adapter or connection. I did do a system restore when this happened a few days ago but since the restore is more then 1month old it is no more.So far i have tried the following:restarting/rebooting router,updating/reinstalling drivers,and many other things but nothing seemed to work i dont understand why it is scanning for wifi but on the mapping it says adapter isnt connected.I have shown a few pics to help you:
Quote: The move to Internet Protocol version 6 (IPv6) could have a profound affect on the Internet, breaking it up into islands of connectivity and threatening cybersecurity in the process, according to Jeff Young, a senior analyst at the Burton Group.
As the IPv4 free address pool continues to dwindle, enterprises can expect to see IPv6-only hosts on the Internet within a three-year timeframe, Young said. In the report, "IPv4 Address Exhaustion: An Inconvenient Truth," Young addresses the incompatibility of IPv4 and IPv6 and some of the problems that need to be addressed during the changeover.

Looks like its time to upgrade from my older Linksys WRT54GX router to a new one. My question is which new routers support IPv6?? How can you tell?? Is there a comprehensive list of new routers supporting it? (If I am to upgrade, might as well get a nice one that supports it).
good/great (wireless) router that plays nice with Windows 7 x64? Something in the sub $200 range. Willing to spend more for a better product. (In doing some research I have seen poor reviews for virtually all routers, no matter the make/brand... so maybe I should be looking for the "LEAST WORST"..LOL)
Currently I have 4 hardwired computers and 4 wireless devices (1 computer, 3 "other"--ipod touch, wii, etc)
i already follow this guide: How to disable certain Internet Protocol version 6 (IPv6) components in Windows Vista, Windows 7 and Windows Server 2008 to disable ipv6. and already try all combination from 0xffffffff until 0x11
0xffffffff will disable ipv6, but listening port still bind to ipv6.
for example, i still can ping ::1 even though that above registry editing should "disable the ipv6". and when i do netstat -an | find "LISTEN", some ports still bind to ipv6, for example:
and so on. anyone have solution to permanently disabling ipv6? the reason why i want to rid of ipv6 listening is because it cause conflicting to my router when want to do port forwarding. i don't have any problem to port forward to other machine installing windows xp/2003. tq.
I recently had a sound problem on the internet in google chrome ( no sound at all although the system sound worked fine). Installed shockewave and reinstall chrome on my pc and reboot my pc all remotely. At this stage my problem with chrome was not solved (although the sound in Explorer and firefox worked). After the remote reboot I could not reconnect to the internet. The local area connection status shows that ipv4 & 6 is not connected anymore.
I tried to turn on and off my network adapter, turn off my firewall and connect my pc directly to my cable modem( instead of being connected to my cisco 4200 v2 router) but nothing! I also tried to restart the DNS Client service and the DHCP client service: still nothing. The windows troubleshoot indicate a problem with the network adapter driver but I doubt it. I am running windows 7 ultimate.
M wireless is flaky to say the least. Realtek 8185 adapter connects sometimes to the interwnt but is painfully slow. Drops connection all the time. My network name changes intermittently between "xxxxxx" and "xxxxxx 2", my network switches between home and public.
I am using Windows 7 Pro and I can't access the Internet My IPv4 is working but I get this: IPv4 : Internet IPv6: No Internet Access
But when I open Browser I get white page but on vBulletin forums I get a 404 error on Every Forum site I go to. So I have a laptop, my brothers computer, xbox360, and my own pc all connected wired to the same router. Recently my PC is unable to get any internet at all from anything, even though it says: ipv4 internet ipv6 no internet access
It shows I am receiving and sending packets but not very often. All my other computers on my network except my one PC, I thought maybe it was my integrated network card on the computer but it seems I am not the only one who has had this problem.
I am on an aspire one netbook and can no longer connect to the internet via wireless or a wired connection. I typed ipconfig/all in command prompt and all I got was..:
Host name: Primary Dns Suffix: Node Type: Broadcast IP Routing Enabled: No WINS Proxy Enabled: No
I do have a desktop and when I ipconfig/all this is what comes up C:Documents and SettingsAdministrator>ipconfig/all Windows IP Configuration Host Name: your-9k1ay6x2a2 Primary Dns Suffix: Node Type: Hybrid IP Routing Enabled: No WINS Proxy Enabled: No
I had a problem about ipv6 on windows 7 for a long time. I have a ipv6 & ipv4 dual stack network. Every time I wake up my computer, the ipv6 cannot work. The appearance is that I can't ping and access ipv6 website. But after some research, I realize that only the DNS part is broken. When I ping the ipv6 site like ipv6.google.com, it tells me it find no host, but if I use nslookup, I can find the ipv6 address. And the following are my tries:
ping ipv6.google.com -- not work ping 2a00:1450:8001::68 -- does work, the ip is the ipv6.google.com address ping -6 ipv6.google.com -- does work like the above
I have a number of systems with various flavors of Windows 7 installed - x64, x86, Home Premium, Ultimate, and so on. Some were factory installs, some were installed by me at various times.Although I manually configured an IPv6 address on each system, they all exhibit the problem of using an automatically-generated IPv6 address instead of the one I have configured. This makes it difficult to connect to servers which use IP addresses for access control, as the automatically-generated addresses change on reboot.[code] one which I have hard-coded, an auto-generated one marked "preferred" and another auto-generated one which is not marked "preferred". When I try to access another IPv6 host on the same LAN, the connection comes from the 2430:1432:1:2:60ee:fe68:8697:cf8a address.I've searched for a way to force Windows to use the IPv6 address I configured and I haven't found anything that worked.
I ordered and downloaded a movie that came in two parts. I could play each part on the computer. However, when I burned these parts to DVD I could not get to the second part to play.So, how can I join these two parts into one larger movie and then burn that to a DVD?I don't want to use the Windows 7 Movie Maker as it doesn't have the proper codecs to play the movie on a general DVD player.
I have desktop with windows 7 professional installed. It is connected thru ethernet. the other computer is laptop with windows 7 ultimate connected wireless. Now I can create a home group on one computer. but I cannot able to join home group from other computer. I have already changed sharing option on advanced sharing tab. I have the same homegroup name, too. Can you please tell me what am I doing wrong?
We have a user who works remotely from home.I would like to add his machine to our domain (as we do in the office) so that he can log in and operate as if he was here.
I can create a HomeGroup from either computer but neither computer can join it,when I run the troubleshooter, on either computer, it keeps telling me "All Homegroup computers must have the correct time," however, both computers do have the correct time and time zone (I even tried synching both w/ the internet time).
i have recently got a brand new machine and have updated from windows xp to windows 7. I have been trying to join the homegroup set up on my parents computer so i can access the printer. My computer is connected to my wired router before going into a ethernet connector in my wall and that then joins the modem. I am using norton internet security and so is my parents computer.
When my computer is plugged into the router and i go into 'trust control' in norton, my router shows up as full trust, but no other computers show up and when i try joining homegroups none show up. But when i plug my computer into the wall bypassing my router, norton shows all the computers on the network and lets me join the homegroup. So to summarise, i cant join homegroups when i am connected to my router, but i can join when i dont use the router.
I'm helping a Dental Office get their current workstations upgraded. All workstations are complete and ready to swap out the old hardware, except i am worried that when the users go to log back into the domain from the new pc's, they won't be able to.
The previous IT guy said they are local profiles, located on each individual PC and not on the server? I thought setting up a Domain was so people could log in from any computer on the network?
How do I join my Windows 7 PC to 2 domains? We currently have our day to day domain as well as a dev domain. when trying to log back into the other domain I get an error message stating something along the lines of a security authentication problem with the workstation. i also changed the dns b/w the 2 so that it would work.
in theory, if i had a laptop and were traveling from my office to an offsite client where i would need a different login, would i have to go through the long route of bringing the pc on and off the domain every time?
I used to have a homegroup set up on computer B, but then i decided to host the homegroup from computer A (my most recent build) because computer A is running more often than any other computer now. So I set it up on computer A and set a password (I know they have to be case-sensitive). When I tried to get computer B to join the homegroup it said the password was incorrect. I know that this isn't the case. Computer C, D, etc. can join homegroup A, but computer B is being stubborn, and can no longer join other homegroups, or have other computers join its homegroup.
So I tried setting up a homegroup on computer B and seeing if computer A could join. Same problem occurred, incorrect password.
Ok so here we go, I have my laptop and pc hooked up with a lan core, and my laptop is sharing its internet with the pc. I want to create a home group so they can share files easy, but when i create a group on the computer (does not mater what computer) the other computer can't find it.
