Has anyone been able to get the SMP beta client working sucessfully on 2008 X64 server?

I am running the fah exe from an elevated cmd prompt with the -configonly switch, it allows me to enter my id, team number and passkey and then it stops responding

If I just run the client, it cannot connect

I have added the two programs to the windows firewall so they are not being blocked

Does anyone have any ideas or is this a lost cause?
