Windows 10: A Network Computer will not accept credenials

I have a private wireless network with three computers all running Windows 10. Two use the same Microsoft account and the third uses a different one but they all show up in File Explorer on the first two. But when I try to open the third one I get a request for credentials. I fill in the window with the name and password for third one but it is not accepted. I'm sure what I entered is correct for that machine. Is there something I need to do on that machine to get what I believe to be the correct credentials accepted?

Thank you?

BTW, the third machine can open the two other machines and show the shared files on them.

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?

We suggest creating a new administrator user account by following the steps
here. Make sure to use the same network settings that you used for your other computers, then check if you can connect to the home network. Since you also mentioned that Windows 10 was freshly installed on this particular computer, have you already downloaded
the latest updates? The latest build for Version 1607 is 14393.1715, and 15063.608 for Version 1703. You can check the build version of your computer by following these steps:

• Click Start.
• Type winver and press Enter.

If you don't have the latest updates, you can follow these steps to install them:

• Click Start.
• Go to Settings.
• Click Update & security.
• Click Check for updates.

If that doesn't work, we'd like screenshots of the network and file sharing settings of the computer that doesn't work, and the settings of one of your other computers that can connect and share files properly on the home network.

I'll be adding a small page on doing this in windows vista soon, since XP is the same with a step or two less, i assume people will figure it out.
