As far as I know, Windows now needs password protected user account if you are using local user account. maybe thats the problem? (it was for me on local home network, I wasn't able to share folders)
Im able to share folders with every computer on the local network. I dont know what did the trick the first time i setup this network but im pretty sure that was the enabling of insecure guest logons.You can share folders without a password, but W11 network security now requires you to change so many different settings to permit it. Sometimes it's just easier to create a password to avoid the headaches.
But now i dont know what else to do, every computer was able to print just fine
