Virtual PC-Server2008R2, VistaSP1 and XPSP3

--Confession--

I did not see a Virtual PC forum (maybe I am just blind), so I posted here.

I have tried various configuration regarding this type of setup, but so far I have not gotten it to work.

I have Server 2003R2 and Vista SP1 and XP SP3 installed in VPC 2007. Vista and XP can ping the server, but the server cannot ping them, nor can they ping each other. I am really just wanting the VM's to see each other, internet access is not a required component for what I am wanting. I have tried various setups (too long to list here), so if someone has the magic config please post if for me. Thank you.
