"HTTP 403" or "0x80040001" error when you connect to a DirectAccess server from a DCA tool in Windows 7 SP1

Applies to: Windows 7 EnterpriseWindows 7 Home BasicWindows 7 Home Premium More


Consider following scenario:

  • You have a DirectAccess Connectivity Assistant 2.0 tool installed on a computer that is running Windows 7 Service Pack 1 (SP1).
  • You use the tool to connect to the DirectAccess server by using One-Time Password Certificate Enrollment (OTPCE) protocol authentication through a HTTPS connection.
In this situation, you can encounter one of the following issues:

  • You receive a HTTP 403 error from the DirectAccess server as a response to the certificate-signing request.
  • You receive a 0x80040001 error after you enter the one-time password (OTP).


This issue occurs because of an error in the validation of the SSL certificate on the client-side computer that occurs before it uses OTPCE protocol authentication. Then, the cached certificate expires and is not refreshed to a valid certificate.


To resolve this issue, install the hotfix that is described in this article.
