Can ping IP and map UNC but can't ping computer

If you can ping ip and make the shared folders using UNC but not ping computer, it is possible the master browser issue. 1) Check any errors in Event Viewer. 2) disable other master browser if you have more than one master browser. (Note: in a small workgroup, you only need
one Master Browser.)

Don't create the username as the same as the computer name

Why some users do not receive your message

After using net send /user to send server shutting down  message to everyone in the network, you were told that some people did not get your message. It is because their messenger service <03> had been disabled. To check if the particular machine's messenger is disable remotely, you can use command nbtstat -a computername. If the messenger service is running, it should show username with <03>. Otherwise, the service is disable.
