DirectAccess is used for internal network connections in Windows 7 SP1

Symptoms

A Windows 7 Service Pack 1 (SP1)-based computer uses DirectAccess to connect to the IPHTTPS address of the DirectAccess Server even though the computer is connected to the internal (domain) network. 

Cause

This problem occurs if the FQDN connection to the DA servers can be resolved in the internal network and if a route exists to the IP address that it resolves to. This problem can also occur if the DA client uses a proxy server that has a route to the DA servers.

Only the IPHTTPS tunnel is connected. The IPSec tunnels are not created inside the IPHTTPS tunnel because the firewall detects a domain profile and because the Connection Security rules do not apply to the domain profile. Although the Windows 7 client did not complete a "full" DA connection, the IPHTTPS tunnel connection still occurs on port 443. Therefore, performance issues may occur on the Direct Access server.
