Hi
is there anyway of sending a quick on-screen message to users on our network to advise of animportant happening. I don't want to use email or im but rather something that pops up on your screen immediately--no reply is needed from the user.

thanks in advance
jim

Have you tried something like:

NET SEND /DOMAIN "Hello Crazy Users!"

I haven't done it, only seen it in the help file, not sure what router/firewall/port blocking issues you'd run into.

Further to usachrisk1983 post, for this to work you need to have to using WINS as well as the messenger service running on all machines.

And keeping the Messenger service on all of the time is not always a security best practice.
You can write a WMI script that can run through your domain computers, if Messenger is off, turn it on, send the message, then turn it off.
Should be pretty simple as it would essentially just be a loop. The only parameter would be the message.

Altough net send is good builtin utility but the problem with net send is if the client pc's have Xp And firewall is configured than it wont work otherwise it is the best & the easient way of sending msgs on network just type
net send 192.x.x.x or net send computername & if u want to send a msg tou All users than net send *.*
hope it might help you

you could use PSEXEC (www.sysinternals.com) inside a script to launch a VBScript somewhere on your network that would pop up a message box with the information that you are wanting to give out.

You could get even more complex if you wanted to.  For example, you could enumerate the OU in AD that has all your computers and try to ping them.  If you get a response back, then you can have it execute the PSEXEC command.  If you don't get a ping back, then you can move on.  This will also make your script go much faster as it's is not trying to communicate with machines that are not on.

Great idea Jared!  Just to put it out there, remember that PSEXEC is not free in a commercial environment, something to keep in mind if that applies to the original poster.

Also, you can save yourself the ping and use PSEXEC with the "-d" switch (double check that) and PSEXEC will launch the application but will not wait aroudn for a result, it'll succeed or fail, but not tell you what.  Goes much faster this way.

Also, I think you can psexec * to send the script to the enter domain.
