Windows 7 - IPv6

Here is my problem, I have a desktop running Windows 7 home premium 64bit and a Samsung N140 netbook running Windows 7 home premium 32bit.
I set up a homegroup on the desktop and attempted to join it with the netbook so I could share the USB printer, after entering the password from the desktop homegroup into the netbook set up it says it cannot join.
So I read the how to's on this forum and found out that on the desktop IPv6 was not enabled, but it has a tick in the box for it under properties and the only option is to install or uninstall, no enable option.
Am I missing the obvious, or is this a common problem.
Any help will be much appreciated.

Hi

Have you tried re-starting both PC's after the configuration changes?

Regards

Yes I tried that and no difference.

This might help with the IPv6 problem.

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.

I have tried everything I could find and nothing works.
It has something to do with Teredo, I also have tried all the things I could find to correct that as well.
So much for the easier way of sharing files and printers on Windows 7.
I have tried for 3 hours to solve this problem and now I give up.

Had another go today, and have finally found out how to get teredo enabled and IPv6 working,and it still will not let me join the homegroup from my netbook.
Alyhough IPv6 is now enabled, it is showing IPv4 as default, any one got any ideas how to make IPv6 the default.

It doesn't really work like that. As it is we all use IPv4 to connect to the internet, that is the default for pretty much everyone right now.
But the 32 bit memory space with IPv4 is limited to 4,294,967,296 (232) possible unique addresses.

The IPv6 protocol is in it's infancy and is currently only used only on the LAN "local area network" and is used for Homegroups only thus far. There are a couple of IPv6 addresses on the internet for testing purposes but thats about it so far.

By comparison the 128 bit IPv6 protocol has an address space that supports a total of 2128 (about 3.4×1038) which is pretty much endless address space. Someday we will make the move to IPv6 for our daily internet connection but that day seems to be a long way off for now.

I'm not sure why you can't join the Homegroup from your netbook, it could be that the netbook isn't capible of joining a Homegroup, but I'll post a couple of links here that might help you figure it out.

I have read the links you posted and thank you for that, but it will still not work.
I have a maplin USB switch and I am going to use that as it is so much simplier.

good plan
