SYMPTOMS
Consider the following scenario:
 * Multiple two-way isolated host adapters run under the same isolated host in Microsoft BizTalk Server 2004. Examples of the two-way isolated host adapters are HTTP adapters, SOAP adapters, or WSE adapters.
 * An isolated host adapter is configured to call an orchestration that is published as a Web service. This orchestration sends a response message to the client.
 * Multiple HTTP worker processes are configured for an application pool in Microsoft Internet Information Services (IIS).
 * A Microsoft SQL Server cluster resource that provides failover support hosts the BizTalkMsgBoxDb database.

In this scenario, after a failover of the SQL Server cluster resource that hosts the BizTalkMsgBoxDb database, new messages are submitted to the orchestration as expected. However, response messages are suspended by the isolated host adapter. Additionally, negative acknowledgement (NACK) messages are generated for the suspended response messages.
