Windows 7: One PC can join, but can not see other Homegroup computers

One PC can join, but can not see other Homegroup computers

Hi,
I'm trying to connect 3 computers - 1 desktop and 2 laptops - all Windows 7 Professional x64.
Desktop wired, laptops - wireless, same router, home network...
Windows Homegroup is working well between the desktop and one of the laptops.
The other laptop can join the homegroup, but ... "No other homegroup computers are currently available".
Anyway other computers and shared folders are visible under Network folder.
Other machines can see each other in the HomeGroup, but this laptop is missing.
I have shared Libraries on every machine.

After hours of investigations I found that when joining homegroup from this laptop, Homegroupuser$ is not created in Control Panel/Administrative tools/Computer management/Local Users and Groups/User.
Also in Control Panel/Credential Manager/Windows Credentials there are no any items like in the other machines (Credentials like MACHINE_NAME\Homegroupuser$)
No third party firewall.
Microsoft Security Essentials - Engine Version: 1.1.9302.0
Windows Firewall - Homegroup allowed.
services - HomeGroup Listener, HomeGroup Provider, Peer Name Resolution Protocol, Peer Networking Grouping and Peer Networking Identity Manager - started, though in Manual mode.
This laptop can create Homegroup and other machines can join it, but the situation is getting worse - no one can see any other machine.
HomeGroup troubleshooter can not see any problems.
I'm considering missing Homegroupuser$ is the problem in my case.
Pls help.

Ensure netbios over TCPIP is enabled on all computers.
Username and password on all machines are the same.
In advanced sharing Everyone permissions are set to full control.

Most likely this problem is caused from rogue files which are collected at peer networking, this is a typical problem and easy enough to solve by simply removing the rogue files at the location in the picture. This tends to be more of a problem with wireless Homegroup connections.

In order to see the AppData file you will probably need to go into the Control Panel then Folder Options, View Tab, click to show hidden files folders and drives, then hit apply.

Using the same user name and password isn't required in order for Homegroup sharing to work.

Remove all files in Peer Networking from All machines in the Homegroup at C:>Windows>ServicesProfiles>LocalService>AppData>Roaming>PeerNetworking, then reboot the machine.

After that leave the Homegroup on all machines then create a new Homegroup and rejoin from all machines.

These files will either prevent you from leaving the Homegroup or joining the Homegroup with the typical error message, "This machine can't be part of a Homegroup" or "No other Homegroup machines are currently available".

Thanks chev65 for the advice, but it didn't help

Same as before - desktop created Homegroup, first laptop joined and everything seems normal.
Second laptop (mentioned in the 1-st post) can join - "This computer belongs to a homegroup", but can not see any other machine, nor they can see it under Homegroup folder.
Anyway it is visible under Network folders of the other computers and Windows is asking "Enter Network Password". So I can access this laptop and can see shared files/folders but only in network folder, not in the Homegroup.

Homeusers group appeared in Local users and Groups (Computer Management), My account become member of Homeusers, but Homegroupuser$ is still not created by Windows.
And Credential Manager is still empty in Windows Credential section.
I suspect same security permissions/policies messed up, but allowing Everyone is not my favourite option.

@TheCyberMan - thanks, but:
- NetBIOS is enabled.
- User names and passwords are different on all machines, I think that this is normal.

If HomegroupUser$ isn't being created and the Homegroup machines aren't showing up in the Windows credentials then there are some pretty big problems some where in the system.

Check everything in the Homegroup trouble shooting link just to make sure.

Have you tried running the sfc/scannow command on the machine with the problem?

sfc /scannow: Windows Resource Protection did not find any integrity violations.
Yes, I know this post in helpdeskgeek.com, everything here checked twice.
Following also done:
Quote:
Just run in a evalated prompt the following command.
secedit /configure /cfg %windir%\inf\defltbase.inf /db defltbase.sdb /verbose
A lot of:
Error setting security on machine\software\classes.
Warning 5: Access is denied.
and some
Warning 2: The system cannot find the file specified.

but Windows said that it is okay to ignore them.

Except security permissions/policies, also IPv6 is suspected, teredo interface also installed

Ping is OK both ways, but Homegroup still empty

So, considering to restore Windows to the factory default using recovery media.

You may try adding the user accounts you are using for sharing and add them in to advanced sharing with the appropriate permissions.

If you have an actual Microsoft Windows 7 disc you may tryan inplace upgrade(repair install) befor doing a factory reset using the guide below:
Repair Install

A repair install will replace the windows folder only and keeps all of your programs and settings and does not wipe anything unlike the factory reset which wipes everything.

If you only have recovery discs which you burned when you computer was new then a repair install will not be possible.

Please back up all your important data before doing either or both of the above such as videos, music, program files etc to an external hard drive or CD/DVD.

Problem solved after factory reset. Now Homegroup works as supposed. Thank you for support and advices.
What can be said? Homegroup troubleshooter working silently, no logging, no output. Many people have problems with this feature. Usual advice from Microsoft - Recreate Homegroup and try again.
Is pressing "Mark as Solved" appropriate in this case?
