Event 2048 When Trying to Connect from French Client Workstation

ID: Q193505

The information in this article applies to:

Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

When you try to connect to an English version of Terminal Server from a French version of Windows NT Workstation or a French version of Windows 95, running the Terminal Server client software, the client get a Terminal Server Client Disconnect message box with the following message:


   Terminal server has ended the connection.

On the Terminal Server, an event 2048 is logged in the System Log:


   The RDP protocol component RDP detected an error in the protocol stream
   and has disconnected the client.

The data section of this event ID shows the following information:


   Data:
   0000: 00 00 04 00 02 00 5c 00
   0008: 00 00 00 00 00 08 0a c0
   0010: 00 00 00 00 00 08 0a c0
   0018: 00 00 00 00 00 00 00 00
   0020: 00 00 00 00 00 00 00 00
   0028: d9 00 00 00

CAUSE

Data encryption is prohibited within France.

When the Terminal Server client is loaded on a French workstation, the client recognizes this and disables encryption, according to French law. When the Terminal Server client attempts to connect to a non-French Terminal Server, the Terminal Server attempts to negotiate an encryption level with the client. The client cannot do this and, therefore, the connection fails.

STATUS

This behavior is by design.

MORE INFORMATION

The same situation exists when you have the French clients mentioned with a French Terminal Server installed as a Member Server in an English domain. If the backup domain controller that will be authenticating the Terminal Server sessions is English with higher encryption (such as 128-bit), the clients will receive the same error message ("Terminal server has ended the connection") and event 2048 will be generated. This is because of the process; the clients are not logging on to the Terminal Server, they are logging on through Terminal Server to the domain. The domain controller negotiates the encryption level from Terminal Server to the domain controller and authenticates the user. Therefore, even though it is French from the client to the Terminal Server, it is French on the Terminal Server to English on the domain controller and generates event 2048.
