I'd like to enter in the discussion... but I need some details.
1) are we talking about 1 server and 8 machines and nothing else?
2) All of them are not connected to Internet, therefore you cannot automatically download the latest definitions, you have to do it manually from another PC outside this network, is it correct?
3) Now you want to deploy these definitions from the server to all clients, obvious. To do this, you need to install the SEP Manager in the server and the SEP client in the clients, of course managed. By default SEP clients take definitions from the SEP Manager. You don't need to touch or set up anything or install LUA, you have only to be sure that the clients can communicate to the server. SEP clients go to the SEPM and, if something is available, they will download it automatically, pushing is not required. Any question?
4) what you have to do is to give the latest definitions to the SEPM in the proper way and it will make them available for the clients and they will take them. Is this what you want?
How to do the point 4:
A) download the only .jdb file available here:
http://www.symantec.com/business/security_response/definitions/download/detail.jsp?gid=savce
B) Move the .jdb file (if it is saved as .zip, rename it as .jdb) to \Program Files\Symantec\Symantec Endpoint Protection Manager\data\inbox\content\incoming folder (default install location) in the server, the rest will happen automatically
C) Repeat every day or at your convenience
I hope I guessed what you need,
Regards,
