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. For additional information, click the article number below to view the article in the Microsoft Knowledge Base:
