如果以下一个或多个条件为真，则可能会出现此问题：

  • SQL Server 未配置为接受远程连接。
  • SQL Server 的必要协议未在 SQL Server 计算机或运行 BizTalk Server 的 SQL Server 客户端计算机上启用。

执行以下步骤可能会解决此问题：

  • SQL Server 外围应用配置工具在SQL Server 2008 上不可用。要在 SQL Server 2008 计算机上为 SQL Server 启用远程连接，请按照 SQL Server 2008 联机帮助中的说明进行操作。

  • 使用SQL Server 配置管理器工具在 SQL Server 计算机上启用TCP/IP和/或命名管道协议。

    1. 单击开始，指向所有程序，然后单击SQL Server 配置管理器。

    2. 单击以展开SQL Server 网络配置，然后单击MSSQLSERVER 的协议。

    3. 右键单击TCP/IP协议，然后单击启用。

    4. 右键单击命名管道协议，然后单击启用。

    5. 关闭SQL Server 配置管理器工具。

  • 使用SQL Server 配置管理器工具在运行 BizTalk Server 的 SQL Server 客户端计算机上启用TCP/IP和/或命名管道协议。

    1. 单击开始，指向所有程序，然后单击SQL Server 配置管理器。

    2. 单击以展开SQL Server 网络配置，然后单击ClientProtocols。

    3. 右键单击TCP/IP协议，然后单击启用。

    4. 右键单击命名管道协议，然后单击启用。

    5. 关闭SQL Server 配置管理器工具。

注意：确保运行 BizTalk Server 的 SQL Server 客户端计算机上的至少一种协议与 SQL Server 计算机上启用的协议相匹配。
