Message staff about - downtime and upgrades
I have to patch Sims again today to fix an issue that needs doing before the census can go.
Does anyone know of a program that can be used for one way communication to all computers on a network so that I can quickly let all staff know of the downtime.
(I will just be running round the school letting everyone know this time)
But for the future does anyone know of anything:
1) Preferably open source
2) Easily installed and run on a network
3) Will popup a message as soon as I send it to all computers that I choose
