Try this for the peer networking problem. The described symtoms aren't the same but this file has been known to cause problems with peer networking so it may be worth a try. I really havn't seen anyone with your exact problem yet.

The fix for this problem seems to be Deleting the file idstore.sst under C:\windows\serviceProfiles\LocalService\AppData\Roaming\PeerNetworking

Once everything at Peer Networking Grouping is running you may also need to do this...

Start the Task Manager
Click on the service Tab
Find the "HomeGroupProvider"
and then stop the service.
You will need to restart after doing this.
Deleting the file fixed the problem for me. I did not have to do the 2nd step.

Thanks.
