Error code when an application uses the CredSSP in Windows Server 2008 R2: "0x80090329"


View products that this article applies to.

Symptoms

Consider the following scenario:
  • You run an application that uses the Credential Security Support Provider (CredSSP) to perform user authentication on a computer that is running Windows Server 2008 R2 or Windows 7.
  • The authenticated user account is a member of many security groups.
In this scenario, the authentication may fail, and the application returns the error code 0x80090329.

You frequently encounter this problem in the following scenario:
  • You install the Terminal Services server role on a computer that is running Windows Server 2008 R2. This computer joins a domain.
  • On the terminal server, the Allow connection only from computers running remote desktop with network level authentication setting is enabled for the RDP-TCP connection.
  • You use a domain account to start a terminal server session to the terminal server that is running Windows Server 2008 R2. The domain user is member of many security groups in the forest.
In this scenario, you cannot start the terminal server session. At the same time, you receive the following error message in the Remote Desktop Connection window on the Terminal Server clients that are running Windows 7 or Windows 2008 R2:
An authentication error has occurred.
The specified data could not be encrypted.
Remote computer: <name of the remote computer>

↑ Back to the top


Cause

This problem occurs because the CredSSP incorrectly encrypts the data when the size of the security token for the user account exceeds 16 kilobytes (KB).

To resolve this issue, install this hotfix on the terminal server that is running Windows Server 2008 R2 and on any Remote Desktop clients that are running Windows 7 or Windows Server 2008 R2.

More information

The Credential Security Support Provider (CredSSP) is a new Security Support Provider (SSP) by using the Security Support Provider Interface (SSPI). The CredSSP enables a program to use the client-side SSP to delegate the user credentials from the client computer to the target server. The target server is accessed by using the server-side SSP. The client-side SSP implementation is currently being used by Remote Desktop Protocol (RDP) 6.1 for the Terminal Services server role. However, the client-side SSP implementation can be used by any third-party program that uses it to interact with programs that use the server-side SSP implementations on a computer that is running Windows 7 or Windows Server 2008 R2.
