• 环境：

          两台server都是 windows server 2012

          IIS 7.0

          SQLSERVER 2014 Enterprise

         .net framework 4.5

• 其它配置：

         windows DTC component 组件已经启用，不需要授权

         两台服务器的防火墙已禁用

还有什么原因会导致这个问题呢？

Hi,

感谢你在MSDN论坛发帖。

从这个错误信息，应该是你使用的COM组件导致这个问题。

这个问题是从windows DTC component 组件抛出异常的吗？ 如果不使用这个组件，还会抛出异常吗？

windows DTC component 组件是这个Configure DTC Security组件吗？

从这个文档中，我们知道DTC组件在默认情况下，是不允许参与电脑远程分布式。

你可能需要配置这个security。

Best Regards,

Hart
