No unmanaged clients require the manual installation of a license file. However, to enable the submission of reputation data from an unmanaged Windows client, you must install a paid license on the unmanaged client. Unmanaged Mac clients and Linux clients do not submit reputation data.
To license an unmanaged Windows client
Locate and create a copy of your current Symantec Licensing File (.slf).
Use the same file that you used to activate your license on Symantec Endpoint Protection Manager.
On the client computer, place the copied license file into the Symantec Endpoint Protection client inbox. By default, the folder in which the inbox appears is hidden, so use Folder Options to enable the showing of hidden files and folders.
On the clients that use Vista or a later version of Windows, the inbox is located by default at C:\ProgramData\Symantec\Symantec Endpoint Protection\CurrentVersion\inbox\
On the clients that run 12.1.x on a pre-Vista version of Windows, the inbox is located by default at C:\Documents and Settings\All Users\Application Data\Symantec\Symantec Endpoint Protection\CurrentVersion\inbox
If the license file is invalid or the license installation failed, a folder named Invalid is created and the invalid license is placed into the folder. If the file is valid, it is automatically removed from the inbox after it is processed.
To verify that you applied the license correctly, check that no files appear in the inbox folder.
Check that the .slf file is in either one of the following folders:
For the clients that run on Vista or a later version of Windows: C:\ProgramData\Symantec\Symantec Endpoint Protection\CurrentVersion\Data\Config
For the clients that run 12.1.x on a pre-Vista version of Windows: C:\Documents and Settings\All Users\Application Data\Symantec\Symantec Endpoint Protection\CurrentVersion\Data\Config
You can also include the .slf file as part of a third-party deployment package.
