홈그룹 작동이상시 점검...펌
HomeGroup is a real pain, to which I fixed on my network recently.
I had it working fine, then it went b00bs north.
On my sons PC to which the problem existed, I removed him as a member of the home group, I then navigated to this address and removed the files within, address is: C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\PeerNetworking.
I then checked all these services were running via services.msc
DNS Client
Function Discovery Provider Host
Function Discovery Resource Publication
Peer Networking Grouping
HomeGroup Provider
HomeGroup Listener
SSDP Discovery
UPnP Device Host
Then I joined my HomeGroup via my sons PC and it worked again.
You can also use various tools, right click the network icon in the notification area and check certain events and problems [Troubleshoot problems].
You can also try tools in HomeGroup or try the 'Microsoft fix it application' too.
If you do succeed and cannot get a network printer working then just add it via Control Panel\All Control Panel Items\Devices and Printers, that works well.
I hope you sort it out as it is a pain in the rear.
