' Script Name - ConfigMgr 2007 Monitor NLB Management Point Health
'
' Purpose - Monitors the health of ConfigMgr 2007 NLB Management Point Servers. The
' health state is reported through Parameter 1 of event
'
' 1700 - An event used to report Management Point health state.
'
' Paramter 1
' (Health State) Condition
' -------------- ---------
' 0 Healthy
' 1 Unhealthy
'
' The following additional events can be raised:
'
' 1100 - An event used only for debugging or tracing.
' 1101 - Script executed successfully.
' 1102 - An error occurred in executing this script.
' 1105 - Accessed denied due to connection failure or permissions.
'
' Assumptions - This script will only run on ConfigMgr 2007 Site Servers.
'
' Parameters - None
'
' Change Hist - Date Version Description
' -------- --------------- -----------
' 05/02/05 05.0.2754.0000 Created
' 07/19/05 05.0.2754.0000 Updated to include WinHTTP status.
' 08/18/07 6.0.5000.2 Added event tracing support.
' 09/21/07 6.0.5000.6 Changed function
' CheckWow64RegistryKeyExists() to
' not just check for the Wow6432Node
' key but also the SMS key under it.
