The Peer Networking Grouping service depends

The Peer Networking Grouping service depends on the Peer Name Resolution Protocol service which failed to start because of the following error:
%%-2140993535

What is this?

Tons of issues with this system after a BSOD and recovery.  Is W/7 Ultimate.

Event Viewer shows related problems.  Tried to activate services that "may" be involved, but no success.  Is more needed to advise on the event view items?  Had Homegroup problems, they didn't want to share and so on; changed settings, modified services and stuck in a cycle here.  Quit sharing files and printers, tried to modify settings and services and still stuck.

Family system, trying to help.

Thanks a lot; please let me know what else is needed.  It's been weeks now and want to resolve before too much more time.

Some have said to run sfc /scannow to repair this error, but would they be willing to get rid of Homegroup and go with user accounts instead?

sfc /scannow run countless times; no problems.

Must have some issues with defaults and services settings.  Unclear and listening

Don't want any Homegroup interfaces; that's where the problems first began.

If that's the case, then I would recommend doing either a repair with the W7 disc or formatting and starting again from scratch.  Even if you correct this problem, the computer is bound to give you more problems on the horizon.

Most of the problems have been resolved; not an option to try either a repair or reformatting at this point.

I plan to return to this system this weekend and will explore further and report back.  

I appreciate your help.

Something which appears to align to this problem is that Internet Explorer loads at startup and we don't want it.  Not our default browser anymore and removed from start up via msconfig, the startup folder is empty; many reboots, yet it persists.

Any ideas how to resolve this?  internet explorer starts automatically at startup windows 7

The same issue remains unresolved as first entered here and to do a Repair at this point is just not an option .

Shall I close this and reopen to get attention?

epichero22 .... Thanks for your input.  Been doing this a long time, and ..of course.. that would be the first step when this run awry.  Not an option.  If it were, I'd not be here asking.

Am I posting this in the incorrect spot?  Should I try instead to escalate to networking?  

I sure appreciate your time, but am looking to resolve without the standard

Clean boot
Repair
Reinstall

At this juncture, not an option.

Further research found these recommendations; but cannot find idstore.sst ...  Is it something we must try in Safe Mode?  Hidden folders are shown.

C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking

Navigate to this and delete idstore.sst

1.Launch Windows Explorer.
2.Navigate to the folder C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking
3.Right-click the file idstore.sst.
4.Left-click the word "Delete".

Alternatively:

1.Click the Start globe.
2.Click Help.
3.Look for help on "Delete".
4.Follow the instructions.

Quick update:  I deleted the idstore and rebooted; also ran all the malware apps including cCleaner which cleaned a number of entries/errors in the registry.  Now at reboot, no matter what I've done, att mail is the first thing to boot using Internet Explorer, before any McAfee even loads.  I've chosen to use Chrome as default browser and checked all start up items, none show me why att yahoo mail loads.  Is this related or some kind of user issue?  I'm truly lost here and appreciate any/all help you can give us.

This is an upgrade from XP to W/7 a few years ago, and a clean/new install isn't an option for them at this time.  That's why I've been working to resolve the issues for the past weeks.

Can you try system restore?

Asta CuTechnical consultant & graphic designAuthor Commented:
System restore is how, I believe, this problem started.  

What does sysinternals and those autoruns to do help, maybe?

Returning to this system early next week, and listening further with appreciation
