The requirements to configure the Direct Access feature in Windows Server 2008R2 is listed here: http://technet.microsoft.com/en-us/library/ee382305(WS.10).aspx
However, it is not clear as to whether all of the required components needed for configuring Direct Access can reside on a single physical server.
Can anyone verify whether all of the server requirements can reside on a single machine?
For example, can the Direct Access server be on the same machine that runs the Domain Name System, Active Directory, IIS etc..?
