If you go here you can download a 90 day trial of Nav 2004
http://go.microsoft.com/fwlink/?LinkId=22028

I'm installing it with this scrip
n:\Nav\Nav2004Trial\Setup\NAVSetup.exe /O REBOOT=ReallySuppress /QB
n:\Nav\update.exe /q
n:\Nav\Norton_WMI_Update\SYMWMI04.MSI /qn

After installing and running through the configuration wizard "Automatic Live Update" is not turned on.
Does anyone know how i can script turning on "Automatic Live Update"
Thanks in advance.

These two files will download the latest virus definitions if anyone is interested.
Still need to figure out how to script turning on automotic live updates if anyones knows how.

create a file called navhome.bat with the content below
del /q e:\Installs\nav\update.exe
ftp -s:navhome.txt
ren e:\Installs\nav\symcdefsi32.exe update.exe

create a file called navhome.txt with the content below
verbose
open ftp.symantec.com
anonymous
nobody@spammer.com
cd public/english_us_canada/antivirus_definitions/norton_antivirus/static
lcd e:\Installs\nav
bin
hash
prompt
get symcdefsi32.exe
quit

Scheldule navhome.bat to run every morning and the file e:\Installs\nav\update.exe will always be the latest virus definitions.

Any idea if this works with earlier versions of NAV?

I haven't tried it in older version but it should work.
If it doesn't it's just a matter of finding the right file in the public/english_us_canada/antivirus_definitions/norton_antivirus/static directory.

Has anyone got any ideas for scripting turing on automitic live updates yet?
