Unable to connect to PC on same network, says wrong password but it is correct

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?

Have you tried using the user name and password word for the user account on the computer you're trying to connect too?

Have you checked all settings? There is a thread that has some good walk-throughs. I'm on my cell phone but when I get home I'll find it and post the link.
