📎 AI Summary:
The thread discusses an issue where a user cannot access their reinstalled Windows 11 PC over the network due to credential errors. Experts explain that Windows SMB sharing does not recognize Microsoft account credentials, advising the user to set up a local account and specify appropriate credentials, including the computer name in the login process. Despite troubleshooting with local accounts and credential formatting, the user continues to experience access problems, indicating that network sharing configuration remains complex.

I have two PCs on my network, Upstairs-PC and Downstairs-PC. Both run Windows 11.

I recently had to reinstall Windows 11 on my downstairs PC.

Since then, even though I believe I have set up sharing as normal, when I try to access \\Downstairs-PC, it tells me my credentials are incorrect.

Both computers are logged into my Microsoft account.

I have tried entering my Microsoft email address as my username, as well as Downstairs-PC and .\Downstairs-PC.

For the password, I have tried both the system password and the password to my Microsoft account. Neither are working.

I have disabled the firewall on both systems, just in case.

Any ideas?

SMB does not understand MS accounts. You will need to setup a local account and grant it access to that share

I have tried changing the account type to a local account on the Downstairs-PC and using Downstairs-PC as the username and the downstairs PC's Windows password as the password but I'm getting the same issue.
