There may be gereral issues with .Net and database access, this depend a little bit what else is installed on your system.

Is this server fully patched, esp. with latest SP for .Net Framework?
Do you use the RTM version of Forefront or with SP1 included?
Is Forefront the same language than your OS? English?

Have a look at the Install log files, if you can find something more there.
