SUMMARY
Using the Messenger Service in Windows gives you varying results that depend on the command options or interface you use to send messages. The method you use determines whether the message is a local Broadcast or a directed datagram, and to which NetBIOS name the message is to be sent.

163409 NetBIOS Suffixes (16th Character of the NetBIOS Name)



NET SEND *
Sends out a broadcast to all registered users of the local domain <00> through each protocol on the sending computer. For example, a computer that runs Windows with NWLINK, TCP/IP, and NetBEUI would send three broadcast messages to domain <00>. A user in the domain that runs all three protocols would receive three messages.

NET SEND /DOMAIN:NAME
Sends out a broadcast to the specified domain name <00> through each protocol on the sending computer. This functions the same as the NET SEND *, with the exception that you can choose a specific domain, instead of using your current logon domain.

NOTE: With NET SEND * and NET SEND /DOMAIN:NAME, only users on the local subnet that belong to the specified domain, receives the message.

NET SEND /USERS
Sends a directed message to the <03> NetBIOS entry for the computer name of each session established with the server. You can view these connections through Server Manager. If a computer has three sessions open under Server Manager, then that computer receives the message three times.

SERVER MANAGER - SEND MESSAGE
Send a directed message to the <03> NetBIOS entry for each computer connected to the server. Unlike the NET SEND /USERS, only one message is sent to each connected computer, even if the computer has multiple sessions with the server.
