# COMMENT: When run, will gather all open HP alerts and mark them as resolved, setting a user 
#	defined comment as well. It will then log to the event viewer it has done so.
#
# NOTES: The "Object Name" we use to determine what rules we want to resolve comes from the
#	MonitoringObjectFullName field of Get-Alert.
#	Also, you'll need to either set this command to start in your SCOM2007 dir (By default
#	C:\Program Files\System Center 2007 or edit Microsoft.EnterpriseManagement.OperationsManager.ClientShell.Startup.ps1
#	in said directory and change the dot source reference from current directory to the complete path. 
#
# When calling this from an OpsMgr scheduled command, use 
# powershell  -PSConsoleFile "C:\Program Files\System Center Operations Manager 2007\Microsoft.EnterpriseManagement.OperationsManager.ClientShell.Console.psc1" -command "& {C:\Script\Path.ps1}"
