Windows 10: Using the same username to access other computers on a network at home

I have two desktop PCs and a surce laptop - all with Windows 10 and connected to the router and each other? via a switch/ethernet. I used to be able to documents on compter A's hard drive using Windows Explorer to navigate via 'Network' on Computer B. Sometime ago somthing changed and I no longer are able to do this.I keep coming up against 'Credentials' and no matter what I try, I can't access the other computers. I've tried adding credentials including username, full name, email ID registered with User on MS. I have the same username, full name and email ID on all the computers. Even so, o

:)

 

One computer cannot access other network computers.


So I've tried every troubleshooting step I know:

• Double checked that Net Bios was enabled
• Ran a bunch of network commands:
  • flushed DNS
  • registered dns
  • pinged and located the named computers successfully
• Reset my router to factory settings

Nothing works when I try to access via explorer. I'm still baffled by the fact that every other computer can access each other AND access this computer. It's just the outgoing connection from this machine that doesn't work.

Any thoughts?

 

Asking for Network Credentials when trying to access computer on the network

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are being asked for credentials when trying to access computers on the network. I’ll certainly help you with the issue.



Ideally, when you are asked for credentials, you will need to enter the username and password of the computer which you are trying to access. If you are on a secured network, you can turn off password protected sharing under Network and sharing options
and you will not be prompted for a password.



If you are unable to access the computer by entering the username and password of the computer, one of thing that I can suggest you is to try entering the Device name and password when you receive the prompt. To check for the Device name, go to
Start >> Settings >> System >> About.



If that doesn’t work, try the steps mentioned below:

1. On the computer for which you are being asked for password, type
   command prompt in the search bar on the Taskbar.
   
2. Right click on the command prompt icon, and select
   Run as administrator.
   
3. Now, type whoami and hit
   Enter.
   

You will get the name of the device, try using the name as the username and use the computer password.



Let us know the results, we will be glad to help you further.
