Windows 8.1 or Windows 7 cannot connect over DirectAccess to a Remote Desktop Session Host server farm

Symptoms

Consider the following scenario:

  • You have a Remote Desktop Services (RDS) deployment.

  • The deployment contains an RD Connection Broker server and one or more RD Session Host servers or RD Virtualization Host servers.

  • The deployment is running Windows Server 2008 R2, Windows Server 2012, or Windows Server 2012 R2.

  • You expose the RDS Endpoint servers to users outside your corporate network by using DirectAccess.


In this scenario, clients can use Windows 8.1 or Windows 7 Remote Desktop Connection to connect to the RD Connection Broker server but cannot connect to their target endpoint in the RD Session Host server farm.

Cause

This problem occurs because the client does not try all the endpoint addresses that are passed in the redirection packet of the RD Connection Broker server.
