I have been having troubles with my homegroup, at home so I decided that would take all the computers off homegroup and make another. When I went to create a new homegroup on my desktop I receive and error message stating Windows cannot set up a homegroup on this computer", and I get this message on both of my computers. I receive no error code when the message box comes up, it just shows this. I have tried deleting and renaming the idstore.sst file several times on both computers and it wont work still. windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking they are both running Windows 7 Ultimate, and both in to my router. Thanks

Assure that there is no HomeGroup in the network and then perform the following steps. 1. Use Troubleshooting tool. Please open Control Panel and click Troubleshooting icon. Click "Network and Internet" and select HomeGroup. Can the Troubleshooting tool find the cause and fix the issue? If not, please move on the next steps. 2. Verify the following 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 Identity Manager" service and choose Properties. c. Please click Stop button to stop the service temporarily. d. Access the following folder: C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking e. Clear all the files and folders inside. f. Start the following service gain: Peer Networking Identity Manager g. Reboot the computer and you should be able to rejoin the HomeGroup. 3. Enable IPv6 a. Open "Network Connections" window, right click the "Local Area Connection" and click Properties. b. Select "Internet Protocol Version 6 (TCP/IPv6)" c. Click OK. 4. Temporarily turn off firewall on the machine. What's the result? Thanks, Novak

Hey I have just done all of that, and nothing has worked. still appearing with the same message. With the IPv6 It says local connection only, just wondering if that would help. But i don't know why this is doing it. I upgraded my router firmware to the latest version to. Thanks

Hi PaRaDoX The regular Internet works with IPv4. Local Network (behind the Router) can work with both. So IPv4 must work, IPv6 is optional. You have to describe your Network, Internet connection, and the application realted to the Internet that you use to shade a little more light on the situation.

Actually, IPv6 is one of Core Technologies Used by HomeGroup. If IPv6 is disabled, HomeGroup will not be created. Hence, it's highly recommended to enable IPv6 first. If IPv6 cannot be enabled, please refer to the following article to modify relevant registry. Home Group Issues Hope this helps.

I have had home groupconnected on my network before, it just was not connecting, and I think that both of the computers were running their own Homegroups. On my network i am running a Dell vostro 1500 laptop(3gb ram, 2.0ghz Dual Core, Win7 Ulti), , and a desktop (3gb ram, 2.6ghz Dual Core Win7 Ulti) I have a Linksys WAG200g router, with the latest firmware build 1.01.09 Both are wired in at the moment, Both have IPv6 Enabled. I can see each of the computers via the network tab, and can share folders that way, also am currently sharing a printer, via the desktop. Anything else you need to know? Thanks so much.

Hi, Just for a check, please try the following: On each computer, please also run the following command in an elevated command prompt to disable Windows Firewall and check the issue: Netsh advfirewall set allprofiles state off Note: you can turn back on with the command Netsh advfirewall set allprofiles state on. Meanwhile, I would like to share the following with you: Why can't I create a homegroup? Hope this helps. Thanks.Nicholas Li - MSFT

I see that it's been over a year since this thread, but I have the same exact problem. Nothing, including anything that I've found in this thread has helped. If there was ever a solution discovered, I'd love to know it. Thanks!
