None of the computers in the workgroup see each other.

I have a workgroup with 8 computers and none see each other.  They are using xp, Win 7, win 8.1, Windows 10.   Some are wired others are wireless.   All in the same workgroup named "Workgroup".  On the Win 7 I have a shared folder shared out to "everybody".   The Win 7, 8.1 & 10 all have Network Discovery and file sharing turned on.   None are on "public Network".    Any ideas why this network is doing this?

I recommend reading John Hurst's excellent article on the subject:
Folder sharing on modern machines

Regards, Joe
JohnBusiness Consultant (Owner)Commented:
Make sure for all computers:

1. Network discovery is ON.
2. File and print sharing is ON.
3. Password protected sharing is ON so that Homegroup is OFF.

Then on the Windows 7 machine, enumerate as users the userids and passwords of the other machines. Permit the shared folders to the user names enumerated.

Also see my article on Folder Sharing

Also, John wrote another article about W10:

Upgrading older systems to Windows 10 - a real world test

Note in the comments under the article that John says this:
Sharing (Folder Sharing I assume you mean) ... is similar in Windows 10 to Windows 8.1. I have a Windows 10 Virtual Machine and folder sharing works fine.

"Do not see" can mean different things. If you aren't able to see any other PC in the network neighbourhood, but can use UNC paths like \\pc1\share1, then it is different from above.

???
Eric AKA NetminderCommented:
I'm just interested -- nothing terribly profound. Our network at home has two Win 7 machines (one of which will probably get updated to Win10 in the next month or two), a Vista machine, a couple of old iPads and even an old netbook, plus a printer or two. So...

Plus one of the Admins asked me to post in a thread to check a process and bug possibility. So rather than have him delete comments after the notifications had gone out... I left it there.

you are trying to enable file sharing across multiple versions of Windows, see below the official document addressing your question.

Networking home computers running different versions of Windows
http://windows.microsoft.com/en-us/windows/networking-home-computers-running-different-windows

basically, XP and all versions after Windows 7 by default use different ways to do file and printer sharing, which may make things a bit tricky if you are unaware of the changes since Windows 7.

an environment with only 7 or higher versions are recommended as you may create a HOMEGROUP with higher security and easier access. be aware IPv6 is required to be enabled on all 7+ computers in the same homegroup.

however, if you do hope to have computers running different versions of Windows, put all computers in the same workgroup, as the instructions given in the official document. also make sure the network locations are correct  (as you have mentioned). just in case of any incorrect firewall settings, you may simply disable the firewall of all computers when troubleshooting the issue.

BTW @Joe, ericpete is "monitoring" this thread for updates, just an old fashion of EE other than using the big-eye button in the left pane.

Ah, that's actually a very nice way of doing it...transparent...lets the players know you're in there. I've always clicked the Monitor button, but this is more civilized. :)

I made sure all are in workgroup, networks are "Work" or "Private".   None see each other still.
JohnBusiness Consultant (Owner)Commented:
On one computer (not the Windows 7 file share computer), open a command prompt and do the following command:

NET USE Z: \\IPAddressofWindows7computer\folder  (folder is the folder share)

What error (specific numerical error) do you get?
syssolutAuthor Commented:
Error 53 has occurred

The Network path was not found
JohnBusiness Consultant (Owner)Commented:
Check your firewall to see if it is stopping you. The error says you are not getting a connection.
syssolutAuthor Commented:
Qlemo, If I try to map \\Windows 7 computer\Shared folder, it says check the name, otherwise there might be a problem with your network.

If I try to ping, either direction (from any computer, or to any computer) it comes up with host unreachable
syssolutAuthor Commented:
John, I shut the windows firewall down on Win 7 computer, but didn't help
JohnBusiness Consultant (Owner)Commented:
That is why I said check firewall because you are not connecting.
JohnBusiness Consultant (Owner)Commented:
Check your workgroup and subnet settings as connection is an issue.
JohnBusiness Consultant (Owner)Commented:
As I noted you are not getting a connection (as opposed to a permissions or security issue). Farther down the list, check the following:

1. In your Network Adapter Properties (in Network and Sharing Center), make sure Client for Microsoft Networks, File and Printer Sharing for Microsoft Networks, TCP/IP V4 are all selected. If you must select some of these, do so and you will have to restart. If TCP/IP V6 is selected, leave it selected.

2. Run TCP/IP Reset:

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Also, ipconfig /flushdns followed by net stop dnscache followed by net start dnscache
Then restart the computer

Do the above 2 checks on ALL computers but most particularly on the Windows 7 File share machine.

I connect up computers routinely so please do all the checks and let's get rid of Error 53

just double check if you have followed every step under below section given in the official document here?
To turn on network discovery, file and printer sharing, and public folder sharing in Windows 7

> If I try to map \\Windows 7 computer\Shared folder, it says check the name, otherwise there might be a problem with your network.

from where? another W7 computer? better test on the same version first.
syssolutAuthor Commented:
John.   I followed your instructions, but is still doesn't help.  

bbao, all those choices are checked off.

The one thing I tried was added my laptop to the workgroup and I connected with one of the Windows 8 desktops.   But that was the only one.
JohnBusiness Consultant (Owner)Commented:
Are you in a position to back up the Windows 7 File share machine and set it up again?  If you really did all these things and your external (router) firewall is not blocking anything, then something has gone wrong with computer.

Did you add all the usernames to the Windows 7 File share machine in the User setup in Manage Computer?
syssolutAuthor Commented:
What should I look for in the router for the firewall?  

The other day the computers all of a sudden saw each other, or at least most of them, but still could not access the folder, except for my laptop, my laptop could access the folder.  Now today, none of the computers see each other.
JohnBusiness Consultant (Owner)Commented:
Look in the router firewall to see if the internal subnet is not being allowed. Normally the commercial routers and firewalls we use do not block internal communications but at least look for blockage at the firewall (subnet not allowed).
syssolutAuthor Commented:
Thank you for all your directions.  But when I could not see two wireless printers from the computers I tried a new Netgear wireless router and now 90% of the issues are repaired.   I was able to create a folder on an external drive, the printers can all be seen and all the computers can see each other.  Thanks again
