Definition update on SEP clients.

Hi,

I'm a little confused about something... It seems the only way for my SEP clients to pickup new definition files is through LiveUpdate.

So although I have both "Use the default management server" and "Use LiveUpdate" checked on our SEPM server, definition files don't seem to be updated using the default management server.

Is there a way I can manually test definition file updates through the management server?

Thanks.
