of the home users have desktop computers. Other home users have laptop computers. All of the computers are joined to the domain. All of the computer accounts
are members of a group named Group1. Currently, the home users access the corporate network by using a PPTP VPN. You implement DirectAccess by using the
default configuration and you specify Group1 as the DirectAccess client group. The home users who have desktop computers report that they cannot use
DirectAccess to access the corporate network. The home users who have laptop computers report that they can use DirectAccess to access the corporate network.
