A few weeks ago we created a KACE pop-up alert to notify our staff of a networking issue. Later that day we created a second alert letting them know that the issues had been resolved. Both alerts had a Keep Alive time of 1 hour. To this day we are still seeing those messages pop up on machines of newly returning staff (those machines that have been off for the last few weeks and are just now being turned on).

Question: Does the Keep Alive field set how long the message will be sent to newly booted machines, or rather is it used to determine how long the message will be displayed on the screen? If it for the latter then is there a way to cancel the current pop-up alerts that are hanging out there?

Thank you for your help.
