Error 0x80040001 When Using OTP on Windows 7 SP1 DirectAccess Clients

Microsoft recently released a hotfix to resolve an issue where Windows 7 SP1 DirectAccess clients fail to connect to a DirectAccess server with the IP-HTTPS IPv6 transition protocol and using One-Time Password (OTP) authentication via the DirectAccess Connectivity Assistant (DCA) 2.0. In this scenario you may receive an HTTP 403 error from the DirectAccess server in response to the certificate signing requests and a 0x80040001 error after entering the OTP.

You can learn more about the hotfix for DCA 2.0 on Windows 7 SP1 and download the associated hotfix here.

Remote Assistance to Windows 7 SP1 DirectAccess Client Fails

Microsoft recently made available a hotfix to address an issue where Remote Assistance connections to remote DirectAccess clients fails. The issue occurs specifically when Windows 7 clients connect to a Windows Server 2012 DirectAccess server using the IP-HTTPS IPv6 transition protocol. In this scenario, DirectAccess clients are assigned a Unique Local IPv6 Address (ULA) using the prefix FD00::/8 for which Remote Assistance service would not listen on. If you are planning to support Windows 7 clients on your Windows Server 2012/R2 DirectAccess server and you need Remote Assistance functionality, you’ll definitely want to ensure that this hotfix is applied to all of your Windows 7 DirectAccess clients.

For more information and to download the hotfix, please refer to Microsoft Knowledge Base article KB2912883.
