System keeps asking for ipv6....

I've been connecting directly to my main machine with this one for awhile now.... (I'm writing this from my media machine in the main room) but I've just been using a direct network connection using my login credentials from that machine. Today I decided to set it up properly with homegroup.

Well homegroup keeps demanding I enable ipv6 even though it is enabled on both machines already.

Any ideas at all?
Problem still persist, can access share folders directly but can not join homegroup without that error popping up.

Have you tried this?
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

My rigs are set up with a "work" network. Either me or "Home" network was not getting along to well. I checked and although my adapter shows IPV6. It shows no internet access. I checked IP config and I had no IPV6 mentioned in the returned results. The reason I mention this is because my net work is not complaing bout no IPV6 access.

Does your router support IPV6?

That's about the only remaining possibility at this point.
It's a good router though I'll have to look into the details on it.
Tunneling is supposed to remove the need for actually device support though.

Thanks for the suggestions unfortunately everything seems straight it's just not joining the homegroup.
I've just taken to doing it the old way and I've just linked media player to the remote folders.
