What is the difference in the local network access by ip and access by netbios-name ..?

Question

System administration

I'm trying to access (SMB) from w10 to server2019 by ip. On one host, it asks for authorization - and after entering it does not authorize. On the second - shows the resources, but does not show the shared folder (Everyone) of the exchanger. By name netbios - everything is visible, everything works ..

Answer 1

In theory, any name is first resolved to the address (no matter how), and then access goes to the address. So if there are no anomalies in the network , then there should be no difference.

Answer 2

Most likely differs in type of authorization. kerberos by name can work, but not by address, for example
