Homegroup joined but no access...

I'm having trouble with my a Homegroup. I turned off my Homegroup to compare transfer speeds between Homegroup and mapped drives. I reenabled it and now it doesn't work.

I have two PCs running W7 Professional. I created a Homegroup on PC1 and PC2 reports a Homegroup is available to join on PC1. I can join the Homegroup. Homegroup reports "joined" in the Networking Centre and "Homegroup" appears in the lefthand navigation pane on open folders. However, clicking on Homegroup returns the message that no homegroup computers are available.

I have...
Verified that both PCs are in the Home network.
Verified that PC1 has directories shared in the Homegroup.
Verified that IPv6 is enabled on both PCs.
Disabled firewalls on both PCs.

Network appears OK as I can see PC1 from PC2 and access directories if I share them the old fashioned way.

I have tried leaving the Homegroup and rejoining with the same result.

Any ideas what might be stopping the Homegroup from working?

Try setting the Library to share folders then share with "Everyone" the link below shows you how. If none of the Library's are shared you will get that message. You need to check this on both machines.
Share libraries with your homegroup

Thanks but that didn't do anything. PC1 (MEDIAPC-PC) Doesn't show up under homegroup on PC2 (SEVEN) but can be see under network. Please see the image below.

BTW. I have shared folders and libraries on both computers but they don't see each other even though both are joined to the same homegroup..

Check the Advanced Sharing settings and make sure it looks like the picture below.
There are two windows that look the same Home or Work and Public. It should say "current profile" at the top of the Home or Work window. You may also need to reboot both machines for any recent network changes to take effect.

Can you access the Homegroup from one of the machines?

Are you using any type of A/V software or a third party firewall?

Settings are identical to yours.

Both computers report they are joined to the Homegroup but neither can see the other. The both list homegroup in the navigation pane once the homegroup is enabled. Homegroup is hosted by MEDIAPC. Both have the default directories shared as well as a couple of others. I've verifided that Homegroup is listed in their shares each time I change anything.

I've tried recreating the homegroup and restarting between each change.

MEDIAPC has no A/V and windows FW. SEVEN has Kaspersky but it is disabled while trying to get this to work.

Bizzare thing is that this was working few days ago.

Make sure that IPv6 is enabled. In services make sure that all the three peer networking services are started.

Yes it is strange that it worked before and not now.

Somtimes it helps to create the Homegroup on a different machine and join from the other but it sounds like you tried that. You may need to uninstall Kapersky also.

Try the link below which is a Homegroup trouble shooting walkthrough. The parts about switching between Public and Homegroup sharing can fix certain problems.

Also try this because it fixed this same problem for someone else.
I had a similar problem. My 64-bit desktop wired into the network and my 32-bit laptop wirelessly connected, stopped recognising one another on the homegroup. Recreating the homegroup and rebooting didn't help.

Then, when I clicked "See full map" in the Network and Sharing Center, I discovered that even though I had set up my network as a Home network and it was displayed as such in the Network and Sharing Center, for some reason Windows 7 didn't "see" that. It wouldn't display the network map because it said I was on a Public network.

So, I changed my network to a Work network, then back to a Home network, and the homegroup started working again. I had deleted the homegroup on the laptop prior to making these changes, so I simply rejoined and everything's now working again.

So make sure you aren't mistakingly on a Public network because Homegroups won't work from there.

IPv6 is enabled on both machines. Peer services are running on both.

Home network is set to trusted under KIS. Cant understand why it would decide to block it now? I'll try an uninstall.

I'm very suspecious of Kapersky really, nothing but problems with A/V's lately and the only way to fix is to uninstall them it seems. Best to install the A/v's after you get the network set up and working.

Try this trouble shooting guide. Pay particular attention to the registry change further down the page. http://helpdeskgeek.com/windows-7/windows-7-cannot-connect-to-homegroup/

We can rule out Kaspersky.

Complete removal, restarted both computers, left and removed homegroup, recreated and rejoined and still the same issue. I can join but cant access from either PC.

OK. I've fixed this

I uninstalled the NIC from device manager, deleted files from C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking and restarted PC2 (SEVEN). Then rejoined Homegroup and it's working again.

Click to expand...

Yes there is one file at C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking that needs to be delated sometimes > "idstore.sst"
After a few failed attempts at setting up a Homegroup that particular file seems to get stuck and causes corruption of the peerNetworking file which somehow completely kills Homegroup functionality. Glad you got it working.

The interesting part is that I don't even have that file on my machine, absolutely nothing where it supposed to be. Of course Homegroups works perfectly for me also so I would guess that file isn't supposed to be there. God only knows why it was ever created in the first place but I think it's clear that we are dealing with a ligitimate Windows 7 Homegroup bug here.
