I have tried to install the user agent on a server 2008 vm and it won't run. I only get an error that says "SF AD user agent Configuration has stopped working" 
 
I have configured the server settings in Policies, User, User Agents on my Defense Center. This is a domain server so the firewall is not on by policy. The event logs are pretty cryptic and don't really say much. The agent never starts so I can't configure it. 
 
There is not much documentation out there for it.
