not checked?
the issue is around here:
Code:

 If Ping($system.tag)
  $system.Checked = "True"
 Else
  $system.Checked = "False"
 EndIf


so, lets make debug code:
Code:

"Pinging: " $system.tag ?
 If Ping($system.tag)
  "Response" ?
  $system.Checked = "True"
 Else
  "system is offline" ?
  $system.Checked = "False"
 EndIf


if the correct text is coming out, the issue is of kixforms nature.
if wrong response, there is something wrong either with the tagged name or the ping() udf.
