Network problem in Windows 11

Hello
Good morning everyone
I have encountered a problem in Windows 11 that has been bothering me for months.
I have a set of systems that are connected to each other in a network and most of them use Windows 10. In this network set, there is a system that I have shared a printer with and all systems can print from it. The system that I use uses Windows 11 - 25H2, but the problem is that unfortunately it could not find the network correctly. After a lot of effort, it finally found the network, but there is another problem that when logging in to the system or even installing the shared printer manually, I encounter a username and password message, while the system where the printer is installed and shared does not have a password. However, I also set a password for that system, but when I enter the password, I encounter the message in the attached picture and it does not log in at all. Please help. Thank you
