I want to exit novell Application Launcher with dos script shell.

I kill NALAgent.exe (taskkill /F /IM NalAgent.exe /T) but icon tray is always up
I kill NALNTSRV.exe (taskkill /F /IM NALNTSRV.EXE /T) but icon tray is always up
I stop Workstation Manager service (net stop ZFDWM) but icon tray is always up
I can close it with a right click on windows desktop.

How can I do it ?

My objective is to restart it : stop and start. Because I modify the registry.

this is the script

net stop ZFDWM
taskkill /F /IM NalAgent.exe /T
taskkill /F /IM NALNTSRV.EXE /T
reg ADD HKEY_LOCAL_MACHINE\SOFTWARE\Novell\ZEnWorks\Zenwsr eg /v ImportServer /t REG_SZ /d {IP_SERVER} /f
reg ADD HKEY_LOCAL_MACHINE\SOFTWARE\Novell\ZEnWorks\Zenwsr eg /v Importws /t REG_SZ /d %COMPUTERNAME%.{OU_TARGET} /f
reg ADD "HKEY_LOCAL_MACHINE\SOFTWARE\Novell\Workstatio n Manager\Identification" /v "Workstation Object" /t REG_SZ /d %COMPUTERNAME%..{OU_TARGET} /f
reg DELETE "HKEY_LOCAL_MACHINE\SOFTWARE\Novell\Workstatio n Manager\Identification" /v "Workstation ID" /f
net start ZFDWM
"C:\Program Files\Novell\ZENworks\NalView.exe"
