... when you create a homegroup you also create a security key. Without giving that key to the other pc to join your homegroup they cannot cannot join even if "Workgroup" are the same.
When I initially set up the HomeGroup on my main system, I created a security key / password. However, when I try to join my laptop to the HomeGroup, I of course get prompted to enter the “HomeGroup Password”. So I enter that password and click on Next. Unfortunately, I then get a message that says: “Windows cannot set up a homegroup on this computer.”
By the way, just for backgroud, the laptop I’m trying to join to the HomeGroup had previously been functioning as part of the HomeGroup. That was a while ago though and I’ve recently re-formatted and re-installed Windows 7 Home Edition. Since the re-install is when I developed this inability to join.
By leaving the network group windows falls back on just having the workgroups match and you manage the settings manually for access.
OK, I now understand there’s a reason for your suggesting “leaving” the workgroup. Not sure though exactly what “leaving” is or how to accomplish that. Sorry, I’m confused about that term.
Inside adavanced setting network discovery has to be on.
“Network Discovery” is showing, i.e. selected, on both systems.
You should see computers at start button and network.
I see no computers listed at anything associated with the “Start Button” on either the main or laptop. At the “Network and Sharing Center” > “View your basic network informaion and set-up connections” display, the main system has “Joined” showing at “HomeGroup”. At the same display on the laptop “HomeGroup” shows “Available to join”.
In Windows Explorer (file manager) at HomeGroup the main system, as expected, reports, “There are no other people in the homegroup”. At the same display on the laptop it reports, “Windows detected a homegroup on your network”. Also, the main system used to show itself under Homegroup, but doesn’t now.
If you still don't see the other computers then there must be some service or protocol service not installed. You can reach services by going to start type services.msc. Be sure to start them and set to automatically start with windows.
I looked at all of the services you listed on both the main and laptop systems. All were set to “Start” and “Automatic” except for “Network Connections” which was “Start” - “Manual” on both systems, so I made it “Automatic” on both. Curiously, “Wireless Zero Configuration” is not present in the list on either system and I don’t know how I’d get it there?
There are also some network card protocols that need to be installed as well. You right click the network adapter and go to properties and use the install button.
Confused about this. Device Manager > Network Adapters shows two listings, one for an Ethernet Controller and one for a Network Adapter. Going to properties for the Network Adapter does not produce an “install button” nor anything about services. Consequently, I’m unable to check the list of network card protocols you suggested. How do I get to that list?
Two last points. I still can’t join the HomeGroup with my laptop. On the laptop at “Network and Sharing Center” > “Change adapter settings” I show my Wireless Network Connection and a “Local Area Connection” (LAN). The LAN is red x’d and says, “Network Cable Unplugged”. The laptop has never had a cable connection that I know of.
Again, Thanks for your help. Christy
