SYMPTOMS

Consider the following scenario:
  • You enable the single sign-on (SSO) feature on a remote desktop server that is running Windows Server 2008 R2.
  • You log on to the Remote Desktop Web Access (RD Web Access) website from a computer that is running Windows 7 or Windows Server 2008 R2.
  • You try to start a Remote Desktop session by using the RD Web Access website.
In this scenario, you are prompted to enter your credentials. However, the expected behavior is that you can start the Remote Desktop session directly.

CAUSE

This issue occurs because SSO in Windows 7 or in Windows Server 2008 R2 is not available for a full remote desktop connection through RD Web Access.

    Collapse this tableExpand this table
    VersionProductMilestoneService branch
    6.1.760 0.20xxxWindows 7 and Windows Server 2008 R2RTMLDR
    6.1.760 1.17xxxWindows 7 and Windows Server 2008 R2SP1GDR
