FIX: Event ID: 1723 occurs when you use Adapters for Enterprise Applications together with BizTalk Server 2006 or BizTalk Server 2006 R2 to process lots of messages

When you use the BizTalk Server Adapters for Enterprise Applications (also known as the Line of Business Adapters) together with Microsoft BizTalk Server 2006 or Microsoft BizTalk Server 2006 R2 to process lots of messages, the following error messages may be logged in the Application log:

Event Type: Error
Event Source: Microsoft Biztalk Adapters for Enterprise Applications
Event Category: None
Event ID: 0
Description:
Error transmitting message: Exception encrypting: Encryption failed with error code: 1723.

Event Type: Error
Event Source: Microsoft Biztalk Adapters for Enterprise Applications
Event Category: None
Event ID: 0
Description:
Runtime Error : Exception encrypting: Encryption failed with error code: 1723.

This problem occurs because the adapters call the Windows CryptProtectData method. However, the CryptProtectData method is not intended for high volume throughput. Additionally, the method handles a maximum of 10 concurrent calls. When the adapters process lots of messages, the adapters may try to make more than 10 concurrent calls to the CryptProtectData method. When this behavior occurs, a failure occurs.
