在“Visual Studio Test Agent Deployment”步骤中出现53异常的原因可能是什么

Question

目前我正在尝试使用TFS2015和vNext构建系统。在“Visual Studio Test Agent Deployment”步骤中出现此异常，我真的不确定该怎么办。

可能导致此异常的原因：

其他远程powershell脚本似乎可以顺利运行。不确定可能是什么。

像往常一样，请毫不犹豫地询问更多信息。

看起来你需要启用文件共享：

在这种特定情况下，RoboCopy工具会报告找不到网络路径，因为我忘记在目标计算机上启用文件共享。一旦我启用了文件共享并再次运行，构建一切都是绿色的，并且我可以验证所有文件都正确地复制到了目标计算机上。

我刚刚遇到了一个类似的问题，问题是我必须在Windows防火墙中启用某些规则，文件共享才能工作。我通过完全禁用防火墙进行了测试，然后尝试通过Windows资源管理器通过"\MachineName“连接到此FileShare

一旦它起作用了，这个错误也就消失了。在这之后，我再次启用了防火墙，并试图找出必须添加的规则。在“高级防火墙”设置中，有一些关于文件和打印机共享的禁用规则，我启用了这些规则并使其正常工作。

希望这能有所帮助
