我在这里写这篇文章，希望有人能帮助我。NServiceBus MSDTC灾难
我想在ASP.NET MVC应用程序上实现NServiceBus。我已经完成了每一步，确保一切都正确无误。我有一个事件将Job Id传递给我的处理程序，然后执行Linq-to-Sql查询并查找作业，然后通过电子邮件发送警报。这个过程非常简单。
但是，我不能为我的生活让MSDTC工作。我不断收到以下错误：
这里是我已经配置了我的公交车：
Bus = NServiceBus.Configure.WithWeb()
.Log4Net()
.DefaultBuilder()
.XmlSerializer()
.MsmqTransport()
.IsTransactional(false)
.PurgeOnStartup(false)
.UnicastBus()
.ImpersonateSender(false)
.CreateBus()
.Start();
我不使用事务，所以我知道一个事实，即MSDTC甚至不应该被调用。
我的处理程序代码如下：
public void Handle(ApplyJobMessage message)
{
if (message != null)
{
using(var context = new MyContext())
{
JobPosting posting = (from c in context.JobPostings
where c.JobPostingId == message.JobId
select c).SingleOrDefault();
}
端点配置如下：
public class MessageEndpoint : IConfigureThisEndpoint, AsA_Server, IWantToRunAtStartup
一切都很正常。消息正确到达时，我做的：
Bus.Send(message);
然而，如图所示出现MSDTC错误：

我试图DTC平并成功的作品，所以我知道一个事实，即MSDTC ISN”问题。我已经读过NHibernate和NServiceBus有类似的问题，但是我还没有能够用LINQ to SQL来绘制任何类似的问题。
任何有关此事的帮助将不胜感激。
我应该补充一点，当我在本地盒子上试用这个数据库时，一切似乎都奏效。现在我很好奇它为什么不能在远程盒子上使用数据库。 – 2011-01-20 09:32:44
Handler机器和数据库机器的操作系统是什么？数据库机器是否允许入站事务？处理器机器和数据库机器在DTC中设置的认证机制是什么？ – 2011-01-20 18:17:15
