Hi, Based on my research, I would like to explain that IPv6 was depended on by the RNRP service. To troubleshoot the issue, let's refer to the following steps. 1. Temporarily disable Firewall and third party antivirus program on the computer for a test. 2. Verify relevant services ========================= a. Click "Start", type "services.msc" (without quotation marks) in Search Bar and press Enter. Note: If you are prompted for an administrator password or confirmation, type your password, or click Continue. b. Right click the "Peer Networking Grouping" service and choose Properties. c. Please check if the service is started; if not, please click the Start button and see if it works. d. You may also choose Automatic next to Startup type. e. Click OK. f. Please repeat the above steps with another service: PNRP Machine Name Publication Service. 3. Modify IPv6 registry key to enable IPV6 ========================== a. Click Start, type regedit in Search Bar, and then click regedit in the Programs list. Note: If you are prompted for an administrator password or confirmation, type your password or click Continue. b. Locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters c. Check whether the "DisabledComponents" registry key exists. If so, let's move on the next steps. d. Double click the "DisabledComponents" registry key and modify the value to 0. (If the key doesn't exist, please create the key above and assign the value 0) e. Exit Registry Editor, and then restart the computer. For more information, we can refer to the link below: How to disable certain Internet Protocol version 6 (IPv6) components in Windows Vista, Windows 7 and Windows Server 2008 Thanks, Novak

I had te "Enable IPv6" problem on both of my newly upgraded to Windows 7 computers. On the PC, this edit of the TCPIP6 parameter worked perfectly. However, on my HP laptop, I performed the edit, then tried to "Join the Homegroup", and I got the same problem. So, I opened regedit again and went to the TCPIP6 parameter and the registry had reverted back to the the original "ff" value for the parameter. I tried the edit several times and even tried rebooting after making the edit a few times. I eventually discovered that the "0" value seemed to revert back to "ff" during the reboot. I also eventually edited the parameter for ControlSet001, 002, and 003 from "ff" to "0" but still got the same result. In any case, I could never get the laptop to join the homegroup because it would always say I needed to enable IPv6. FYI, IPv6 is enabled in the properties of the network adaptor. Is there some other copy of the registry somewhere that iI am missing that could be causing this? I appreciate any help you can provide.

Just a Note here Create a DWORD -> DisabledComponents "# Note If the DisabledComponents entry is unavailable, you must create it. To do this, follow these steps: 1. In the Edit menu, point to New, and then click DWORD (32-bit) Value. 2. Type DisabledComponents, and then press ENTER. 3. Double-click DisabledComponents. # Type any one of the following values to configure the IPv6 protocol, and then click OK: 1. Type 0 to enable all IPv6 components. "

This is nice information to have just in case I run into this situation while trying to help others get their Homegroup up and running. Thank you.

I have done everything you suggest, but still cannot create a homegroup. I STILL get the IPV6 error message. I have a desktop with Windows 7 and a laptop with Windows 7. When I try to change the value in TCP/IP6 parameter from ff to 0, it reverts back as soon as I exit. I've spent at least 5 hours on the phone with tech support from both computers, and with Costco Concierge tech support (which is excellent, BTW), and no one has been able to fix this. One tech person says Microsoft is aware of this problem, but has not issued a patch. Is this a MS problem? If so, why hasn't it been fixed by now? Are there other places to change IVP6? Any other ideas for me. Surprised that others have had success with this.

SOLVED I had exactly the same problems, i'd get the network and homegroup working, then i'd restart one of the pc's then nada Easy fixed though open regedit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters change disablecomponents to 0 then right click on the parameters folder and click on permissions unclick all fullcontrol permissions to all the users/groups apply repeat to all networked pcs restart DONE! PS you still need to ensure that the services Peer Networking Grouping and PNRP Machine Name Publication Service are on automatic

Thank you, thank you, thank you, Novak Wu and yogi2200 ! Those changes made the fix stick on all my 32-bit PCs! However, before it would stick after a reboot on my 64-bit PCs, I had to change DisabledComponents in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters to a QWORD (64-bit) binary zero value instead of a DWORD (32-bit).

This answer not only fixed my issue with not being able to join the home group but also resolved the problem I was having with streaming to my Xbox 360 with Media Player 12. Thank you so much.

I have the exact same problem on my Dell laptop, everytime I restart, the DisabledComponents parameter resets to ff? Every other setting is correct and all the services are started and on automatic. I have the most recent drivers for wifi card and am using Zonealarm free and AVG free. Disabling these makes no difference. Win 7 Pro x64, Intel WifiLink 6300 Someone please help, homegroup is completely useless to me???

I'm glad I stumbled on this thread as I haven't been able to enable IPv6 either but your solution worked for me too. Thanks!

I have been researching the issue on why IPV6 would not start for weeks. This post answered the question and worked. Thank you

Hi Guys had the same problem on my HP Pavilion. looking around the web an answer came up that it could be ZoneAlarm. Go to firewall settings/ Blocked zone secuity/ advanced and tick enable ipv6 network. It worked for me.
