Can't share a folder on a local network in Microsoft Windows Server 2025 STD

We have two Microsoft Windows Server 2025 Standard (Version 24H2, Build Number 26100.32995) servers in our Active Directory.

We can't share folders; it constantly asks for a username and password. We've tried every solution, but nothing worked. I found a similar thread, but the solutions there didn't work either.

How can i solve this sharing problem ?
