Microsoft Forefront won't turn on

I am at home with a work machine and cannot get Microsoft Forefront Endpoint Protection 2010 to turn on.

If I go to my Start Menu >> All Programs >> Microsoft Forefront Endpoint Protection I get its main screen. In the center of the screen is a big red button that reads Turn on. When I click it, the program hangs for about 45 seconds, and then gives me the following error message (code 0x800705b4):

Is MFE a client-server application? If so, I am wondering if I am getting this because I am not VPNed in (and thus, can't connect to a server). If not, what does that error code mean? I searched for it but nothing really turned up.

Forefront is designed to be run in an environment with a server in place; while there are ways of getting it to work otherwise, presumably yours isn't configured that way. I would suggest trying again on the VPN.
