There are times when one of our applications is down for maintenance and we'd like to let our users know about it before they start flooding our help desk with calls. What's the best way to notify our users of an event on the network?
Some users are on our intranet, while others log in from the Web. Is there an application they can install to which we can send notifications messages?
I'm interested to hear what others have come up with to address this requirement.
