I'd like a utility that:

- Sits in the Windows system tray.

- At specified intervals (specified in seconds such as 5, 10, 30, 30, 90, 120) it pings a specified IP address.

- If, after a specified timeout (specified in milliseconds or seconds), there is no reply, the tray icon changes to indicate a problem. Optionally, it would play a sound.

I'm sure such a utility must exist, right? I was unable to locate one in a quick Google search. Must not have got my terms right or something.
