If you want to install Antigen on an Exchange server that doesn't have access to the internet to install updates there is a work around, see the steps below:-
Create the UNC Update Folder structure.
· Create a directory that is named "Forefront."
· In the Forefront directory, create a directory that is named "Engines."
· In the Engine directory, create a directory that is named "x86."
· In the x86 directory, create a folder for the engine on which you are working.
For example, create a folder that is named "Norman."
· In the %EngineName% directory, create a folder that is named "Package."
An example of the UNC Update Folder path is as follows:
Download the latest scan engine files.
