MSDTC只在一个方向工作

Question

我正在尝试TransactionScope用于单元测试,并且我在构建服务器上不断出错.在关注了几个有用的SO答案和博客之后,我安装了DTCPing并在两个server1&上运行它server2.当我以相反的顺序运行它时,它似乎在一个方向上连接而在另一个方向上失败:

++++++++++++Validating Remote Computer Name++++++++++++
Please refer to following log file for details:
    D:\KPAHQDEV043372.log
Invoking RPC method on teamcity
RPC test is successful
++++++++++++RPC test completed+++++++++++++++
++++++++++++Start DTC Binding Test +++++++++++++
Trying Bind to teamcity
Binding call to teamcity Failed
Session Down

但是当我按照预期的方向运行它时,它就失败了

Please refer to following log file for details:
    C:\TEAMCITY3024.log

Problem:fail to invoke remote RPC method
Error(0x6BA) at dtcping.cpp @303
-->RPC pinging exception
-->1722(The RPC server is unavailable.)
RPC test failed

我在这里找到了一些有用的信息,但现在我只是卡住了.有任何想法吗？

Answer 1

您需要在防火墙中添加分布式事务协调器服务作为例外。另请确保 RPC（端口 135）已启用并在防火墙中添加为例外。

您还可以通过关闭防火墙并重新运行 DTCPing 来检查防火墙是否是罪魁祸首。
