Windows 7: Can't join Homegroup

12 May 2010   #161

Windows 7

Check that your computer names are unique! And not just case-different, but unique.

I battled this problem on my dad's desktop / laptop for 4 hours and tried the IPV6 and the reboot sequence tips and they didn't work. Then I noticed the computer names were identical, and thinking that might confuse Win 7 I changed one and poof! It worked! (You are forced to reboot after you rename a computer so it could have been that, but I rebooted 10 times before with no success).

I didn't confirm the problem since my dad was getting irritated and I figured Microsoft had stolen enough of my life at that point. But give it a try. Unique computer names are needed. Can anyone else confirm?

PS - Hey Microsoft, if unique names are required for Homegroup to work, could you TELL US THAT! Dang.

For the posts about homegroup problems. Make sure that the 2 pc's you are trying to use on the homegroup have different pc names. ie; you cannot connect to the workgroup if both pc's have the same name "john-pc" for example. win 7 will think that this is the same workgroup thus you cannot join only create. To change the name of one of your pc's go to control panel> system and security> system, next to computer name go to change settings, when the system properties box opens click "change to rename this computer" Make sure it is different from your other pc. You will the be able to JOIN the homegroup. Hope this helps.

Hi commando your problem there is both PC's have the same name. change one of them by clicking Start then right clicking Computer and click properies, click Change Settings next to the PC name, give it a different name, (even just putting a 2 on the end will work) at the moment Homegroup is getting confused and thinking they are the same PC

Check the clock settings

I had this same problem, network was fine.

My issue was the clocks - they were about a minute off (desktop said 8:27; laptop said 8:26. Why won't WIndows allow you to display seconds in the taskbar clock???)

Anyway - laptop was set to sync to a NIST server for time, and hadn't manaaged to connect. Desktop was syncing to Set the laptop to sync to the same server as the desktop, forced a time sync on both machines - and suddenly I could see my homegroup on the laptop!

Thanks all for the suggestions - the troubleshooter did highlight the problem, but it's easy to assume the clocks are in sync if they LOOK the same ...

Interesting thank you mheney, I didn't realise that the clocks needed to be exactly the same as well. I'll add that to my list of troubleshooting tips

Windows 7 Ult, Windows 8.1 Pro,

1. If your can't set up a Homegroup or if file sharing with Homegroups is inconsistant follow these instructions. First you will need to uninstall completely which ever A/V software or third party firewall you have installed. Or you can try going to your A/V's software forum and attempt to configure your A/V's for sharing with Homegroups. This problem is listed first for a good reason simply because it's the most likely cause of set up or sharig problems with Homegroups.

It might also be helpful to reset your router. Be sure that IPv6 is enabled in your network connections properties window "picture below". Enable DHCP in your routers set up page and make sure that all your machines are using the same default gateway and subnet mask and that all the intended Homegroup machines can sucessfully connect to the internet.

2. After sucessfully completing those tasks use the link below to help you fix the most likely problems encounted when setting up a Homegroup network. Pay close attention that the Time/Date settings are in sync on all machines and also that the bios clock is in sync. Also notice the registry adjustment which is sometimes required to fix certain Homegroup set up problems.

Homegroup trouble shooter walkthrough in the link below.

Set Network Location to Home

Another reason why you can’t access your HomeGroup is because it only works for home networks where you trust all the computers. If, for some reason, you chose Work, Public, or Domain, then HomeGroups will not work.
Click this bar to view the full image.

3. There are several reasons why you can’t access your HomeGroup. Here are the most popular reasons for not being able to connect to your HomeGroup. If none of these troubleshooting tips work, try restarting your computer, or leave and then re-join the HomeGroup.

4. Other times there is a rogue file causing problems with Homegroups.

Open Windows explorer and navigate to the following file.

C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking and delete all of the files in this folder. Now restart the computer.

Go to Services again and you should be able to start 'Peer Networking Grouping' and 'Peer Name Resolution Protocol'. Restart the computer again.

When you log on this time, check the event log again, to ensure no errors concerning the two services are present and also check Services to ensure the two services concerned are running.

You should now have full functionality restored to your homegroup.

5. There are a few more things you can do if it's still not working.

Open up a command prompt and type "regedit" without the quotes then hit enter. Navigate to the following key.

You have to set the DisabledComponents Dword to 0

Very important> If there isn't a disabled components dword you have to create one and then set it to zero. To do this follow the next step while you are still at the same spot in the registry.

In the right pane, right-click and select New – DWORD (32-bit value) and type in it's name as> “DisabledComponents” and set its value to 0.
“0″ = Enable All IPv6 Interfaces (Default)
After that reboot your machine and see if the problem is fixed.

6. The following services need to be started for Homegroup networking to function properly. It sometimes helps to change them from Manual to Automatic.

First open a command prompt and type in services.msc then hit enter. Scroll down the list and locate the following services. Make sure that the service is started then right click on the service and choose properties, set the service to Automatic rather than Manual.

Right click the sevice, go to properties, make sure that all these services are started then Set to Automatic> DNS Client, Function Discovery Resource Publication, SSDP Discovery, Peer Networking Grouping,Peer Name Resolution Protocol, UPnP Device Host services, Homegroup listener, Homegroup provider.

For wireless connectivity with Windows 7, you need to run the network setup wizard for everything to work correctly.

You should also make sure that your Advanced sharing settings are set like the pictures below. The public sharing window may not matter with Homegroups but it sometimes helps to set them up accordingly.

Here are a few tutorials from Brink to help you navigate though the Homegroup set up procedure.
