Error code when an application uses the CredSSP if the authenticated user account is a member of many security groups on a computer that is running Windows Vista or Windows Server 2008: "0x80090329"
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 or Windows Vista.
The authenticated user account is a member of many security groups.
In this scenario, the authentication may fail and the application returns the 0x80090329 error code.
You frequently encounter this problem in the following scenario:
You use the Remote Desktop Connection utility on a client computer that is running Windows Server 2008 or Windows Vista to try to log on to a terminal server that is running Windows Server 2008.
On the terminal server, the Allow connection only from computers running remote desktop with network level authentication option is enabled for the RDP-Tcp connection.
The user account that you specify in the Remote Desktop Protocol (RDP) client is a member of many security groups.
In this scenario, you cannot start the terminal server session. Additionally, you receive the following error message:
An authentication error has occurred (Code: 0x80090329).
This problem occurs because the CredSSP incorrectly encrypts the data because the size of the security token of the user account exceeds 16 kilobyte (KB).
To resolve this problem, install this hotfix on the client computer and on the server. A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article. Apply this hotfix only to systems that are experiencing the problem described in this article.
