Hi David,
I'm afraid Symantec has made some security changes which means that this link no longer works. Firstly the ftp site support.altiris.com no longer exists/works, and the one they've moved to is password protected. This change hasn't been advertised (anywhere I can see) so I guess we're all meant to have developed telepathy in order to be notified of such updates.
It's also a bit shocking considering this is live linked inside Deployment Server.
The new ftp site is: ftp.altiris.com
I have PM'd you the user name and password to gain access to the secured site. If anyone else has this problem -just PM me and I'll pass you the details too.
In the mean time this has been escalated, so let's see what happens.
Kind Regards,
Ian./
