long time ago i was able to send short MESSAGE using run / command PROMPT in a place that using LAN by typing something at the command prompt like...."netsendpc02*hello?*"and then it just popup out from the pc02....now i just forgot it!
anyone can help?
Maybe something like net send pc02 Hello ?no....it wasn't...is was something more like this

netsendpc02*hello?*

(i remember that the star included)
& other symbol...how can i forgot such thing..uh

i try it long time ago in windows xpDark Blade is right, the command for that is net send pc02 hello butyou can put your message in inverted commas if I'm not mistaken.

net send pc02 "hello"

I think this is so you can use /'s in your message without the command prompt thinking you are trying to specify a parameter.ok,i done that but guess what?it said
file sending no longer supported
something like that........ i found this
http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/net_send.mspx?mfr=true
but can anybody give me example how it is written?
i dont understand it much.

Examples
To send the message "Meeting changed to 3 P.M. Same place." to the user robertf, TYPE:

net send robertf Meeting changed to 3 P.M. Same place.

To send a message to all users connected to the server, type:

net send /users This server will shut down in 5 minutes.

To send a message that includes a SLASH mark (/), type:

net send robertf "Format your disk with FORMAT /4"

can you send to an ip address or does it need to be on the same network ?

Notice that since XP SP2 the messenger service (not to be confused with Windows Live/MSN/Windows messenger) has been disabled by default. So if it isn't working this is probably why.
