I have 4 networks. 10.22.227.0\24, 10.28.43.0\24, 10.0.3.0\24, 10.0.6.0\24. In total there is some where around 250 users. What i would like to be able to do is send the user a message from my computer or my laptop. I used msg from the CMD line and Net send from the CMD line. This is great and all but really only works well with in the local lan and at best its a 50/50 shot.
I do not (at this time) have a DC or AD set up. All sites are networked together through a site to site VPN and a Fiber Tunnel. All the Computers are Win 7 Pro & 10 Pro
Is there another way i can send messages to users even if i need to install some small (light weight) software (preferably free) would be fine.
