How do I use the net send command on my server 2003 standard edition?

I have server 2003 with AD plus 100 sessions of clients with different Windows operating systems though some have windows vista and others have windows 7. I want to send for them an info message for administration use.

I am trying  to use the below command:

NET send /USERS xxxxxxxxxxxxxxxxxx   but unfortunately it is giving me the following error.
"an error has occurred while trying to send ....."

thanks in advance

Hi nabilhamoud,

Use the command as follows:

NET SEND * (Your Message)

Do not include the brackets...

This will send a message to all users. Also make sure that the Messenger Service is running on your server and the client machines.

B Rgds,

Net send is not supported in Vista or Windows 7.

stinkyPete is completely wrong, I'm on Windows 7 now and can send/receive net send commands.
