Thinking about setting it to a workgroup now, since i read here somewhere that the transfer speeds between workstations might increase then.

Windows 7 x64

Hello there,

just found this discussion when seeking around for solution for the same problem.
Unfortunatelly all listed solutions don't apply to my problem. I can't start PNRP Machine Name Publication Service because Peer Networking Identity Manager couldnot be started. If I try to start this manually, I get Error 5: Access was denied

If I look to properties it is started under Local Service credentials. I'm aware to switch to local user account because of possibly losing LS password.
C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking folder doesnot exist,

If I attempt to create home network, I get the progress window lasting forever, no errors in event log during this action.

Any one can find a solution?

I had the exact same issue. Finally solved it by changing the 'Startup Type' for Homegroup Listener from Manual to Automatic.

Go to Start Menu>Services
Scroll down to find HomeGroup Listener
Double click on whatever is chosen under the Startup Type column and you change it that way.

I had this problem as well and had all but given up. Tried all the solutions given to no avail until I manually restarted my upnphost in Services. It was stopped so I manually restarted it and then even though I wasn't able to manually restart p2psvc or p2pimsvc. I was able to use the homegroup troubleshooter and the pop-out network troubleshooter started by the homegroup one to start them.

Then I restarted my computer and was able to do all of the things related to homegroup.

I literally created this account just now to post this answer as I've had this problem for a LONG time now.

It was through the answers here and a quote from Shinmila H that I figured this out.

I'll post that quote for further reference here.

In order for the HomeGroup networking feature to be working, there are certain Windows services that need to be enabled and running. If you used a program to disable services or manually disabled them, it may be causing the problem.

The services that need to be turned on are listed below:

• DNS Client
• Function Discovery Provider Host
• Function Discovery Resource Publication
• Peer Networking Grouping
• HomeGroup Provider
• HomeGroup Listener
• SSDP Discovery
• UPnP Device Host
You can turn on the services by clicking on Start and typing in “services” and then clicking on Services.
In the Services dialog, double-click on the service and make sure the Startup type is set to Automatic and click Start to turn on the service.

Router Supports IPv6
This is pretty much not an issue anymore, but just for the sake of covering all bases, you need to make sure that your router can support IPv6 protocol. If not, Windows 7 cannot communicate with the other computers using HomeGroup. Any relatively new router will support it, so unless you have a really old router, you should be ok.

Run Network troubleshooter
This is to ensure if the connection failure is due to low network signal or no signal.

Try updating your network card driver to what is compatible with Windows 7 so that there is no conflict.

Check your manufacturer details from DirectX Diagnostic Tool:

1. Open the Direct X Diagnostic Tool. To do this, click Start, type dxdiag in the Start Search box, and then click dxdiag.exe in the Programs list.
2. Click the Display tab.
3. Under Device, look for Name and Manufacturer.
4. Click Exit.

Make a note of the manufacturer, visit the website and download the appropriate driver for your graphics card driver that is compatible with Windows 7.

Windows 7 Home Premium x64

If these didn't work for anyone, as it happened to me, there is a final pro tip from some genius on Microsoft Answers :

I had a similar issue just recently and none of the fixes mentioned anywhere worked.
First thing was to figure out exactly what clicking "Leave the homegroup" does. I opened Process Monitor, added a filter to include results from explorer.exe (as that's the process that spawns the control panel window) then started capturing. Clicking on that link caused explorer.exe to create a new thread then destroy the thread with nothing in between, so I disabled the filters and saw that it was calling svchost.exe. svchost.exe then traversed the registry until it hit a snag. One registry key was giving an access denied error.
Instead of fiddling with permissions, I exported that key, deleted it, then re-added it, and lo and behold, no more access denied error. After this, I did the usual routine of stopping the three Peer* services, deleting the C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking folder, then restarting said processes. This time, clicking on Leave the homegroup worked as intended. With a few more tweaks (disabling and stopping the two HomeGroup services), any mention of HomeGroup in the navigation pane in Explorer was gone.
Ironically, starting the HomeGroup Listener service still gave me some about %%-2147023143. But nevertheless, I'd fixed my issue so all was well.
When in doubt, bust out Process Monitor.

Windows 7 Ult, Windows 8.1 Pro,

To fix this problem it's actually required to remove ALL FILES which reside in the PeerNetworking folder, not just the idstore.sst file, and you must do this for all machines that were connected to the Homegroup.

I know this because I've fixed the problem myself and just removing the idstore.sst file isn't enough to fix the problem in all cases.

This location > C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking won't be viewable unless you go into Folder Options at the Control Panel then click on the View tab, then set to "Show all hidden files and folders" which will allow you to see the AppData folder so you can get to the PeerNetworking folder.
