How do I create a Simple online/offline monitor

Question

I have seen many examples of ping monitors with a backside t-sql database to store ip addresses. If I have the exact fqdn or IP addresses that I would like to monitor with a ping loop or a timed ping loop. How would I write the vb in order to use a green light red light method to indicate that each server was either connected or disconnected.

Sincerely,

Chris

For Example,
on the form it would look like this

(Server Connection Status)

Server Name = Green/Red
Server Name = Green/Red
Server Name = Green/Red

This would load and start automatically when the program is opened, and would cycle under its own thread so not to slow or make the application freeze during the ping loop lets say every 60 seconds per each server / ip.

Catch generatedExceptionName As Exception
Me.pict_logonServer.BackColor = Color.Red

End Try
If logonServer.Connected Then

Me.pict_logonServer.BackColor = Color.Green

How would I create the Green or Red indicators using the successful replies? If you could provide an example that would be awesome.

The simplest is a label which you change the ForeColor of.
