I am trying to RDP to Windows Server 2012 from Android 4 tablet. I am using PPTP and the default VPN client. I can establish the VPN connection just fine. I can ping the server both by name and IP. RDP fails, times out after couple of minutes. VPN/RDP from a Windows client works. I have also tried RDP on the LAN with Android and that works too. So its the combination VPN/RDP/Android that somehow needs to be the cause. Ideas? Perhaps an alternate PPTP VPN client?
