The unmanaged Windows agent setup program installs an agent on the local Windows computer.
When you manually install an unmanaged agent on a Windows computer, the unmanaged agent attempts to connect to the central computer that you specify in the setup program. An unmanaged agent identifies itself to the central computer at the time of the first successful connection. However, the central computer does not accept communication from the agent until you authorize it with the Agent Administrator.
NOTE:
You cannot install an unmanaged agent on a Sentinel Agent Manager central computer or user interface computer. However, you can install an unmanaged agent on a database server.
You cannot install Sentinel Agent Manager components on a computer that already has an unmanaged agent installed.
