Cannot create a homegroup or join one properly
So sometime within the last month or so I noticed my laptop was starting to act funny when trying to access files over the homegroup on my desktop--it was asking me for my credentials every time I restarted the computer, and wouldn't remember them
even when I checked the box.
As best I could tell it was using my computer's name as my domain, so when I typed in the username/password I also had to type in the "domain" of my desktop, which was simply its name.
Anyway, I didn't think much of it until recently I wanted to fix this problem, and I noticed more problems.
I first removed both computers from the homegroup.
Then, I tried to make a new homegroup on my laptop.
But attempting this results in the
error message "Windows cannot set up a homegroup on this computer", and no error code at all.
However, I can still create a homegroup with my desktop, and I can even join that homegroup from my laptop.
But after joining, I cannot access the video/audo/photo folders that are shared on the desktop and the icons for them are generic, not the
unique ones for each folder type.
However, once I share any additional folders from the desktop, I can then access all the folders from the laptop, once I have entered the same login information it had started asking me for weeks ago.
Oddly, my desktop can
access those same folders on my laptop without any trouble, as could my wife's laptop!
I have scoured the Internets looking for answers.
I've tried several solutions, but to no avail.
Just to be clear what I have tried so far:
deleting everything in the \Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking folder and rebooting
checking the correct services were turned on.
ensured all computer names are different
tried two different routers, in case it was a hardware problem (one router is the one on which I had no problem using homegroups until a month ago)
checking IPv6 is enabled, and adding the registry edit mentioned elsewhere to ensure it is enabled.
the usual homegroup troubleshooting, on both the laptop and the desktop
deleted all my Windows credentials
synced the clocks/timezones
tried using a wired connection.
The desktop is on wi-fi as well, though, and has no problems.
I think that's about it.
I may try my oldest system restore if no one else has any other ideas, but I'd rather not do that.

How to Avoid Downloading Malware
Where are you getting the download?
There are malicious people who download valid copies of a popular download, modify the file with malicious software, and then upload the file with the same name. Make sure you are downloading from the developer's web page or a reputable company.
Don't install download manager
Many sites suggest or require you to install an installer or a download manager before allowing you to download a program you may be interested in downloading. These tools almost always cause your computer more problems and may even have malware or other spyware. Avoid any site claiming anything must be installed first before you can continue with your download.
Avoid advertisements on download pages
To help make money and pay for the bandwidth costs of supplying free the software, the final download page may have ads. Watch out for anything that looks like advertisements on the download page. Many advertisers try to trick viewers into clicking an ad with phrases like "Download Now", "Start Download", or "Continue" and that ad may open a separate download.
Cancel or deny any automatic download
Some sites may automatically try start a download or give the appearance that something needs to be installed or updated before the site or video can be seen. Never accept or install anything from any site unless you know what is downloading.
