Question:
Can I activate the network environment to see all clients in my network environment?
Answer:
Yes it is still possible, but absolutely not recommended.
If you still absolutely need this, you have to do the following at your own risk
ucs set samba/min/protocol=NT1
/etc/init.d/samba restart
With Windows 11 you have to adjust you Windows, too
In your powershell:
Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol
