Symantec Endpoint protection 12 client protection can be installed with no problem on all computers , am I right ?
Yes you can install it without any problems.
What about the "server" XP Professional and Symantec Management Console ... As far as I know I should install IIS . I will do it using the Windows XP Pro CD . Except from installing IIS do I need to configure it ? Do I have to do something else ?
-> in XP you can have only one website running at a time; just install IIS , install Management console it will configure the necessary virtual directories;
