TCP/IPv6 and homegroups - TCP/IPv6 is enabled, but homegroup says that it is not.
I have three computers with Windows 7 Home Premium installed recently and works well. I want to create a homegroup. When I try to join one of the computers to an existing homegroup, I get the message "your network must have IPv6 enabled connection". I have tried the stop and restart, TCP/IPv6, but I can't the homegroup to work. I cut off all firewalls. How can I verify that TCP/IPv6 works, and how I can fix this problem if it is not.
The homegroup on two other computers worked without any problems. All are connected by ethernet cable to a Verizon FiOs router. The computer problem has no other problem of connectivity - internet and e-mail work correctly. I also see the computer of 'bad' on the map of the network on the part of others.
Hi SandyGrim,
Welcome to the Microsoft Answers site.
one) that you get an error message? If Yes, what is the exact error message?
I would like to explain that IPv6 has been dependent on the NPRI (redundant network routing protocol) service. To resolve this problem, we will see the following steps.
Step 1:
Temporarily disable the firewall and third-party antivirus on the computer for a test.
Step 2:
Check the relevant services are enabled.
1. click on "Start", type "services.msc" (without the quotes) in the search bar and press ENTER.
2. If you are prompted for an administrator password or a confirmation, type your password, or click on continue.
3. right click the "Peer Networking Grouping" service and choose Properties.
4. Please check if the service is started; If this isn't the case, please click on the Start button and see if it works.
5. you can also choose automatic next to startup type.
6. click on OK.
7. repeat the above steps with another service: PNRP Machine Name Publication Service.
Step 3:
Modify the key to register IPv6 to enable IPV6
Important: This section, method, or task contains steps that tell you how to modify the registry. However, serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click on the number below to view the article in the Microsoft Knowledge Base: 322756
1. Click Start, type regedit in the search bar and then click regedit in the list programs.
2. If you are prompted for an administrator password or a confirmation, type your password or click on continue.
3. Locate and then click the following registry subkey:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters
4. check if the "DisabledComponents" registry key exists. If so, move on the next steps.
5. double-click "DisabledComponents" registry key and change the value to 0.
(If the key does not exist, please create the above key and assign the value 0)
6. exit the registry editor and then restart the computer.
For more information, we can refer to the link below:

Hi, I discovered I can no longer change the firewall settings or turn on Windows Defender... I get an error code 0 x 80070003 "cannot change the settings. Windows Defender will also not start by saying that it cannot find the path. The Base filtering engine is running in components and firewall services and the advocate are set to automatic but is running.
I did a sfc/scannow from an Admin command prompt, but found no errors.
Thank you

Original title: access to the Windows 7 firewall problem
Hello
You don't give us enough information on what anti-virus or anti-virus Suite you use.
Thanks for the reply...
I am very prudent and wise when online and regularly scan my computer with scanning of Microsoft System but I find too slow the computer anti-virus programs don't have for the moment.
That's why I am a little concerned that I can't access the settings of firewall or defender.
I also refused access to my files in the file manager even if I am the only administrator and user.
So I still have the problem
Tony

problem with connecting to the internet
whenever I try to connect to my internet I get 'local internet only' and when I try to repair it it says that there may be a problem with your dns server, I looked for a solution for centuries now, and no one can seem to help me! Please someone help me?Hello
First off I'm going to assume that when you say "local internet only", you really mean "local only". Also, I'll assume you are using a router for internet connection broadband. If I am wrong, then you will have to describe the answer how you try to connect to the internet more in detail.
First of all, your router. The indicators show that there is an internet connection? Consult the manual, which probably came on a CD with the router. Internet connection led can resemble a planet with rings or a circle with a lower-case i in the middle of it, or some other symbol. It can also have a caption saying 'internet' or 'connected '. If the router is not connected while your PC will not have access to the internet.
Click the Start button and type "cmd" then press ENTER. In the window type (mainly black) which results in ipconfig and press to enter. Transcribe the results of the command ipconfig for a response.
Your (wired or wireless) network card is set to automatically get an ip address? Otherwise, set it to do that and also to get information from DNS server automatically...
- Right-click on the icon network at the bottom right of your screen, and then click Network and sharing Center
- In network and sharing Center, click on manage the network connections (on the left)
- Right click on 'Connect to the Local network' or 'Wireless Network Connection' depending on how you connect to the router
- Click on select Internet Protocol Version 4 (TCP/IPv4), and then click the properties button
- If things are not set to 'automatic', please note all numbers so that you can restore the settings if necessary
- Make sure that "Obtain an IP address automatically" and 'DNS server automatically get an address' is selected, then click OK
- Click on close
If you are using a wireless connection, what happens if you try to connect to your router with an Ethernet cable?
Please post back with your comments to the above and give more details about your configuration, i.e. router brand and model (or another material of Internet), if you connect wireless or with an Ethernet cable, etc. etc.

deleted the windows on windows defender and impossible to reinstall! Message comes out and says that I should not install windows defender, because it came with windows vista. How can I try to fix it when I have windows Defender on my computer?
You can not delete Defender in Vista.
It is part of the Vista operating system.
You can only activate / it:
http://Windows.Microsoft.com/en-us/Windows-Vista/turn-Windows-Defender-on-or-off
Enable or disable the Windows Defender
Many anti-virus have conflict Defender (McAfee, AVG, etc.), and turn it out / conflict with it.
Microsoft Security Essentials, it turns off because it has its own version.
See you soon.
