NETWORKING WINDOWS 10

Problems connecting to network computers?
Pop-ups asking to enter Windows Network Name and Password
Nothing you do will work, no matter what credentials are entered???
HERE IS THE SOLUTION...proven many times with my own computers for many years!

First...be certain networked computers are all running without NordVPN running <--- not certain...

GO TO ALL COMPUTERS IN NETWORK
Rt click Windows start, type services.msc
Locate the following services and double-click on the service to open its properties.
Click in the "Startup type" and change startup to Automatic (delayed start)
(These following settings fixed all 3 of my computers MANY TIMES..jt)

Make sure that the following services are set to Automatic (Delayed Start)
AND click PROPERTIES for each and then click tab
RECOVERY and change each entry to RESTART THE SERVICE...

Go through the following services:
Function Discovery Provider Host (FDPHost)
Function Discovery Resource Publication (FDResPub)
Network Connections (NetMan) *
Peer Name Resolution Protocol (PNRPSvc)
Peer Networking Grouping (P2PSvc)
Peer Networking Identity Manager (P2PIMSvc)
Server
SSDP Discovery
UPnP Device Host (UPnPHost)
Workstation
and
Control Panel\All Control Panel Items\Programs and Features>>
--> Turn Windows Features On or Off:
Find SMB 1.0 CIFS File Sharing Support (Expand)
Only Select "Tick Box", SMB 1.0 CIFS client, OK.

Network Tip: I had all kinds of problems with one computer not showing up in my networkz
I could PING the computer but not connect through the computer name
I renamed the computer's name, and voila...the computer appeared.
BINGO...the missing computer showed up. This has happened twice over 5 years.

These are the hierarchal steps up from ping:
ping
nbtstat -A serverIP - if fail, check 135/139/445 (TCP) and 137/139 (UDP) open <---Failed for me, so I simply changed Computer Name
nbtstat -a servername - if fail, check DNS/WINS is ok
net view \\servername

SEQUENCE TO RESTART ROUTER and MODEM NETWORK
UNPLUG POWER from MODEM and ROUTER wait 2 minutes
PLUG IN MODEM and wait 2 minutes and all lights are on
PLUG IN ROUTER wait 2 minutes
This fixed networked computers not showing in network
----------------------------------

See all networks here...delete unused networks
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
------------------------------------------
Enter Windows Network Name and Password
will not work, no matter what credentials entered...
How to get network sharing work with Windows 10
------------------------------------------

I have been struggling with this problem for days, I have tried everything recommended, in addition to anything else I found on google.
I managed to fix it, the problem was group policy was not defined.
Changed "Enable Insecure Guest Logons" to enabled, now I can finally access my shared folders.
Windows, Run, gpedit.msc
In the console tree, select Computer Configuration > Administrative Templates > Network > Lanman Workstation.
For the setting, right-click Enable insecure guest logons and select Edit.
Select Enabled and select OK. Not certain about this????
------------------------------------------

Be certain all updates on both computers are downloaded and installed...no pending windows update installs.

Netgear Nighthawk Mesh Router
...and probably ALL routers....
MOST BASIC NETWORKING FACT
To connect Windows NETWORK COMPUTERS...
If one computer is connected to Internet with Ethernet
And other is connected with Wireless
That is DIFFERENT networks, and local computers will not connect- even local networks are on different networks...
So must have ALL computers same connection method to internet.
----------------------------------|

Also to use NordVPN with the NordLynx servers - which are faster type,
after uninstalling and COMPLETELY reinstalling
Go to c:windows\Program Files\Nordvpn and allow through Windows Firewall Control each .exe file...
----------------------------------|
Click Network icon in lower right Taskbar...be certain only ETHERNET is on...do not connect to wireless AND Ethernet.
TIP...Internet Explorer, Right click Network, Properties...shows all the networks.

SET IT UP WITH VPN ON and then leave it on...or network will disconnect..

1. Windows Settings, Network and Internet, Network and Internet Sharing Center, left side of screen change advanced sharing settings...Turn off password protected sharing.
2. Public sharing, turn on sharing so anyone with network access can read and write...
3. Run elevated PowerShell,enter:
netsh advfirewall set rule group="Network Discovery" new enable=Yes
4. Control panel, right click System, Advanced system settings, Computer Name, Network ID, this computer is part of business network.
Choose...My company uses network without a domain, Workgroup should say my name WORKGROUP.

Netgear Nighthawk Mesh Router....NO WiFi network found?
Nighthawk Router
NO WIFI
Open router Windows setup page,
Type in browser 192.168.1.1
admin
Newburgh12
Then ADVANCED tab, Advanced Setup, Wireless settings, UNCHECK Enable AX, then click Apply. <Unsure yet - Enabe AX is what males Router FASTER...I had to update network driver!
(tech support says, ADVANCED, Setup, Wireless Setup, 2.4ghz channel...channel 11?? 5gz channel...161?? ) <Unsure yet
!!!! Then ADVANCED, REBOOT router!!!!
----------------------------------

NordVPN and MOST VPN services must be un-connected
Then networked computers will connect
IF NOT, I mapped out networked computers when networked was connected
Click the Quick access folder - look for network computer name and Volia..the missing network appears.

Problem setting services manager To AUTOMATIC?
ERROR windows could not start the peer name resolution protocol on local computer
Go to "C:\ProgramData\Microsoft\Crypto\RSA" and then rename "MachineKeys" folder to "MachineKeys-old".
Create a new folder "MachineKeys" and right click the "MachineKeys" folder , select "Properties" and click "Security" tab. then
set "Full Control" permissions to "Everyone".
----------
Be sure to check BOTH computers are on the same network name? If not, do below...
----------
PRIVATE OR PUBLIC NETWORK will not change?
--->>>>>NETWORK problems that just won't work? <<<<<----
BE SURE TO CHECK COMPUTERS ARE ALL ON SAME NETWORK NAME
i.e.: Ethernet Desktop computer connected through Ethernet CABLE.
Other computers on network connected WIRELESSLY
so
Desktop computer must be connected thru Ethernet cable for Internet
AND IN ADDITION
Desktop computer must be connected to same wireless network...
In order to connect with other computers on same network!
and do the following for ALL COMPUTERS ON NETWORK:

Sometimes this selection to change between Private and Public network profile is missing from Settings / Networks page. In that case profile must change by PowerShell.
Right Click Windows Icon (Start button) and open PowerShell (Admin) and use following commands to get interface index number and change profile to Private (or Public):
Get-NetConnectionProfile

Set-NetConnectionProfile -InterfaceIndex <index number> -NetworkCategory Private

or 
Set-NetConnectionProfile -Name "Network_Name" -NetworkCategory Private
Enter network name without quotes

The following one doesnt always work:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
When you find the ProfileName of the network you want to change to Private, double-click on the Category DWORD on the right-hand side:
Change the ‘Value data’ from 0 (Public) to 1 (Private) -- REBOOT
---------> BETTER YET ---> I deleted ALL the files in the Profiles registry directory above which worked best! jt YES!!!! <----------
----------

When updating drivers on Dell websites if you need NETWORKING display etc. drivers,
BEST TO search for ALL drivers for EACH CATEGORY
Download and them all Voila...

BINGO...the missing computer showed up.

Win 10 Networked computers not shown in Network?
Do a network RESET

scroll down to Network Reset and allow time for the settings to propagate

Be certain both computers are on Private Networks
Windows settings, settings, Network & Internet, click on appropriate connection name,
Find the connection (ie: NETGEAR79, rt click it, Look for Network Profile, Private)
----------------------------------------------------

Start, Network Connections. Right click on "Ethernet" (or whatever connection is being used) and left click on properties.
Scroll down to "Internet Protocol Version 4 (TCP/IP)" then click on Properties.
Local Area Connection Properties
Make sure the "Obtain an IP address automatically" and "Obtain DNS server address automatically" radio buttons are checked.

Be certain DHCP Enabled
Click OK.

-------------------------------
Go to Control Panel, Network and Sharing Center, click
Connections, Ethernet (or whatever's in there) , Properties, scroll down to
