Note that you need to use a single back-slash character between the domain and user names.

Resync Windows 10 login and network passwords

Windows 10 sometimes changes the local login password but not the network access password when a user modifies their password. The following Windows 10 steps should get you back in sync again:

  1. Launch the Settings app and click on Accounts.

  2. In the "Your Info" section click "Sign in with a local account instead" and create a new local account. This will log you out when complete.

  3. Log back in using the new local account and repeat the steps but click "Sign in with a Microsoft account instead".

  4. Use your Microsoft email address & password in FileBrowser to connect.
