Looking for a way to notify users that we will be logging on to their machines to perform troubleshooting /work. Currently we VPN then RDP in and log them off mid work flow. This is in server environments. During these periods we cannot call the office as it’s during lunch and office phone goes to voicemail. Besides calling every employee’s cell phone are there any ideas? We do have OCS running but not sure if we could run that on the server and also open to other solutions. For some reason net send is not working. Thanks!

i can get this to work. the only way i can get msg to work is if i do msg * [your-message] and that only tests it/sends it to the server no other computers. they only have one win 7 box...i made a mistake and put this into the win7 catagory because we predominantly work on win7. so this envir. is sbs 2k3 and xp sp3 machines.

net send /domain:s1 hello --works, but i can't send to specific computers or i am not getting the syntax right.

msg * hello -- works, but this exact syntax does not help me communicate with other computers either. when i tried this in elevated using your syntax (msg /server:[computername] console [your-message]) it failed. There is no error...it just provides another cmd line as if i simple hit enter.

both of the above syntaxs should show the message on all computers, right? but they do not. only the server has it displayed.

Doesn't that bring up security issues though? That is why i though, in general, messanger service was disabled.

That is what i thought too. I don't want to open a vunerability just to send a simple message. Are there security issues with msg? maybe its safer to just add another user to OCS. Your thoughts?

FYI: I found that for security measures I should block the ports: 137,138,139 in my firewall between LAN and internet.

Does msg service need messenger service enabled?
