Homegroup connect IPv6 no network connectivity
- Laptop & Desktop using Win7, cannot connect to Homegroup on the desktop because IPv6 is not enabled. I check the adapter and it shows a checkmark next to IPv6 protocol yet the troubleshooter tells me I need to enable IPv6. What am I not doing correctly?

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.

- Open regedit and go to Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\TCPIP6\Parameters
If you have a key labeled DisabledComponents delete it. Reboot your computer after removing it and see if it works. Hi,
