More homegroup problems

Also verify that the date and time are correctly set on both computers.

Uninstall AVG completely; you can always install it again. AVG has created problems for some folks trying to network and others have had no problem with it. At best you will be able to connect; at worst you will have eliminated AVG as the problem.

1. First you will need to uninstall completely AVG or which ever A/V software you have installed, and I mean every last file on all machines.

2. If that doesn't work go through the check list in the link below first. Pay close attention that the Time/Date settings are in sync on all machines and also that the bios clock is in sync. Also noticed the registry adjustment which is sometimes required.

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.

• Your computer might not be connected to the network the HomeGroup is on. Make sure the computer has network/Internet access. Try having Windows 7 troubleshoot the Internet connection for you.
• Your network location might not be set to Home. Learn how to check and change your network location if needed.
• Network Discovery might be turned off. Learn how to turn Network Discovery back on.
• Other computers in the HomeGroup might be turned off.
• Other computer in the HomeGroup might not be sharing files. Learn how to share files using HomeGroup.
• Maybe someone changed the HomeGroup password. Try checking the HomeGroup password on other computers in the HomeGroup. If the HomeGroup password was changed, change the HomeGroup password on your computer.
• Your computer might not yet be joined to a HomeGroup. Learn how to join or create a HomeGroup.
• Turn off or uninstall any third party firewalls or A/V software (usually bundled with antivirus software) that are installed on your computer.

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.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters]

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, 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,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.

I never needed to turn off the Windows firewall and Homegroups always seems to work for me but then again I never tried installing a third party firewall or an A/V software.

Yes that list is comprehensive and it took me quite awhile to gather up all that info. In most cases going through that list will solve the problem. I suspect there is something blocking the connection but it's hard to guess at it from here when I can't even see the machine. It's probably just one small thing preventing access like a remnant from an A/V or third party firewall. It could even be a router problem but that is less likely.

You may want to type ipconfig /all into a command prompt on all your machines to make sure they are all using the same default gateway. Resetting the router can sometimes fix these types of problems if it's working right, or even installing new firmware can help. You can post the results here so we can have a look at it. It should look similar to the picture below.
