Win 7 Homegroup/TCPIP6 problem.

[RastaJon]

Hello,

I'v been having an annoying issue on one of my win 7 boxs regarding TCPIP6.
For some reason TCPIP6 is disabled from the registry. This can be fixed by altering the DWORD DisabledComponents at the following location,

HKEY_LOCAL_MACHINE\SYSTEMurrentControlSet\services\TCPIP6\Parameters

from 'ff' to '0'. After rebooting TCPIP6 works and im able to connect my box to the homegroup.

Thats all well and good but the next time the system is re started the DWORD reverts to the origional value of 'ff', meaning i have to repeat the process.

Is there any way i can avoid this teadious routine as its quickly becoming a chore.

Thanking you in advance

Hi RastaJon,

this may help by disabling any firewalls and auto starting the 2 services http://social.answers.microsoft.com/...1-c4cf41244597

Hi Techsent,

Thanks for your reply, unfortunately my problem still persists.

Heres a bit more detailed info about my sytem settings.

• Windows 7 Ultimate x64.
• IPv6 is enabled in Network Sharing Center.
• Network Discovery is enabled.
• My network connection is set to Home.
• My router supports IPv6.

The following services are all set to Automatic and started.

• DNS Client.
• Function Discovery Provider Host.
• Function Discovery Resource Publication.
• Peer Networking Grouping.
• PNRP Machine Publication Service.
• HomeGroup Provider.
• HomeGroup Listener.
• SSDP Discovery.
• UPnP Device Host.

As i mentioned in my last post editing the DisabledComonents DWORD fixes my problem completely. Untill the next restart.

What i am looking for is a way of forcing this DWORD to stay set at '0' rather than reverting to 'ff' on restart.

Any ideas?

I read ya. This may work.

1. Copy everything between the lines below into notepad.

--------------------------

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]
"DisabledComponents"=dword:00000000

-------------------------

2. Save the file into the c:\ drive as tcpipv6.reg

3. Open regedit and drill down to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

add a new string value named

force tcpipv6

within this new string value, add the value data

regedit -s c:\tcpipv6.reg

4. reboot twice to test

The use TCP/IPv6 depends also on other computers on the Network.

Sharing per-se does not need the TCP/IPv6.

When configured on peer-to-peer Network. Win 7 have three types of Sharing configurations.

Home Network = Works only between Win 7 computers. This type of configuration makes it very easy to Entry Level Users to start Network sharing.

Work Network = Basically similar to the previous methods of sharing that let you control what, how, and to whom folders would be shared with.

Public Sharing = Public Network (like Internet cafe) to reduce security risks.

The Work Network is the one that most of us are going (and need) to use.

Win 7 Work Network's Sharing settings are in principle similar to Vista's configuration (some menu in locations in Win 7 might be in different place, and look a little different, but it should not be a problem for a compute to adopt)

So, maybe this can Help.

Make sure that the Software Firewall on each computer allows free local traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should be Off, and the active Firewall has to adjusted to your Network IP numbers on what is some time called the Trusted Zone (consult your 3rd Party Firewall instructions.

When finished with the setting of the system it is advisable to Reboot all the hardware including Router and all computers involved.

Hi guys,

Sorry about the delay, i'v been busy at work.

Techsent,
I was so confident when i saw your solution, it was exactly what i wanted to do. Unfortunately it didnt work. tcpip6.reg works pefectly when double clicked, but the force tcpip6 string does not seem to be applying it on start up.

I'v included sceengrabs for you, mainly just to check that i aint made a stupid mistake.

Thanks for the reply.
I was considering that route, but as all the boxs on my network are win 7. Two thin clients for media streaming, my main computer and a media server. I thought the homegroup route would be quick and easy, and it was, untill i moved my media from my main box to the server. This is the box with the annoying issuses.

It just didnt seem worth changing the whole setup of the network considering all im currently doing is streaming media and it is working fine apart from this damn DWORD.

I think now i'm more annoyed that my system has decided it knows better than me and will revert my changes at the first chance it gets. I will not be beaten.

Any more ideas on how we can make this DWORD accept its fate and remain set at '0' or figure out why its changing back and stop it.

Thanks again for your help guys.
