The syntax of this command is:



NET SEND {name | * | /DOMAIN[:name] | /USERS} message


Sends messages to other users, computers, or messaging names 
on the network. The Messenger service must be running to receive messages.

You can send a message only to an name that is active on the network.
If the message is sent to a username, that user must be logged on
and running the Messenger service to receive the message.

name                   Is the username, computername, or messaging name 
                       to send the message to. If the name is a 
                       computername that contains blank characters, 
                       enclose the alias in quotation marks (" "). 
*                      Sends the message to all the names in your group. 
/DOMAIN[:name]         Sends the message to all the names in the 
                       workstation domain. If name is specified, the 
                       message is sent to all the names in the specified 
                       domain or workgroup. 
/USERS                 Sends the message to all users connected to 
                       the server.
message                Is text to be sent as a message.

ommy could you clarify that question ??

I mean, it's OK to use more then one line in a question..




NET SEND * "Allways remember if the world didn't suck we'd all fall off"

is allway's fun in a large corporate windows 2000 network..

BTW as usual, I'm not responsible for your stupidity..
And you won't be the first corporate drone fired for this kind-of-prank..

There are so many days where I have to beat myself over the head to stop myself from doin that. Well different line, but same thing.

Some more info (not included in the help):

This works fine:
C:\>net send 192.168.1.152 hello
The message was successfully sent to 192.168.1.152.

If the receiving systems has the messenger service turned off:

C:\>net send 192.168.1.152 hello
An error occurred while sending a message to 192.168.1.152.

The message alias could not be found on the network.

More help is available by typing NET HELPMSG 2273.


A minor note, the server serice does not need to be running on the target machine.

i think ommy means how does a message get to the recipient !

well net send is based on netbios which is a braodcast based protocol that is sent out onto the network and when the bic encounters it it looks at the packet to see if it contains the address info such as ip address or netbios name of the machine and if so it will keep it if not it will then send it on the network (in milliseconds of course) and as for the senders address it is too from the netbios name etc. there is also the hardware mac address that is supposedly unique to all nics.

for more info look up netbios and broadcasts etc along with all the other protocols as you are a nebie.

welcome and live well and love life

before anyone berates me for not explaining the osi layer i was just brimming over the top of the process so as to not complicate things !

Heh, you can get a NetSpoof off cnet.com, just a trial, but it's interesting program...

im not sure i understand the question but ill give it a shot as well.

the message service accepts messages from anyone. it waits. it dosn't "know" one is coming it just accepts it when it gets there. the information sent with the message contains the name of the sending machine (with the standard send utility) which is why a name appears as "message from"

the number of machines that accept messages and their IP address change from moment to moment so a standing data base wouldn't be practical but the message service listens on port 137

it seems spammers use multi-threaded devices and send their message out to an entire IP range. the reply is logged for the success rate but the device dosn't wait for it. it just keeps on sending...bastards


hope this helped

[yuna_admirer]
