Code:
$RC = AddKey ("HKEY_LOCAL_MACHINE\SOFTWARE\Public Domain")
$RC = AddKey ("HKEY_LOCAL_MACHINE\SOFTWARE\Public Domain\Blat")
$RC = WriteValue ("HKEY_LOCAL_MACHINE\SOFTWARE\Public Domain\Blat", "SMTP server", "$SMTPServer", "REG_SZ")
$RC = WriteValue ("HKEY_LOCAL_MACHINE\SOFTWARE\Public Domain\Blat", "Sender", "helpdesk@@uk.bsmg.com", "REG_SZ")

$RC = WriteValue ("HKEY_LOCAL_MACHINE\SOFTWARE\Public Domain\Blat", "Try", "3", "REG_SZ")
$RC = MessageBox ("Norton AntiVirus may have a fault on this machine." + chr(10) + "Please call your local IT helpdesk and ask them to check", "Defwatch.exe missing!", 48, 300)
Shell "blat NAV_Fault.txt -t $AlertAddress -q -s NAV_fault_on_@WKSTA_during_logon_by_@USERID" ; email the helpdesk to report the find

Thanks for any advice - I'm going to look at postie and see if that's any better.
