COM OBJ错误：虽然DTC配置

我有一个使用COM OBJ错误：虽然DTC配置

using (TransactionScope ts = 
       new TransactionScope(TransactionScopeOption.Required, 
        new TransactionOptions { IsolationLevel = System.Transactions.IsolationLevel.ReadCommitted })) 
      { 

... 

       ts.Complete(); 
      }

我收到以下错误一些C＃代码。你知道为什么吗？

令人敬畏的异常消息，详细和不说。 E_FAIL糟透了，除了“无法做到，不知道为什么”之外没有任何意义。每个人使用Java代替COM +的主要原因。你需要微软支持，如果修改配置或魔术SO帖子不解决它。 – 2011-12-22 15:21:37

如果启用了防火墙，请确保它已配置为使用MSDTC。如果不是这样，重新安装MSDTC，正如user9 ...所暗示的，有时会神奇地修复它。 – 2011-12-22 17:45:30

[TransactionManagerCommunicationException：与底层事务管理器的通信失败。] - 这表示MSDTC未安装或未正常工作。你可以尝试安装/重新安装MSDTC并启用它。
