MORE INFORMATION

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 threebroadcast 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 eachprotocol 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.
