【问题描述】：

当我们尝试在服务器 2008 上加载时，我们遇到了一个 .NET 2.0 Web 服务应用程序的问题，该应用程序正在生成未找到模块的异常。运行相同 2008 版本的第二台服务器可以正常加载该服务。 作为调查的一部分，我们采用了默认的 hello world .NET 2.0 Web 服务并将其部署到两台服务器上，并且存在完全相同的问题，即它在一台服务器上运行良好，而在另一台服务器上运行良好。问题是试图追踪有问题的模块。运行 process explorer 和 dependency walker 似乎并没有给我们任何线索。

完整的错误是：-

[FileNotFoundException：找不到指定的模块。 = （来自 HRESULT 的异常：0x8007007E）] System.Reflection.Assembly._nLoad(AssemblyName 文件名，字符串 = codeBase，证据 assemblySecurity，程序集 locationHint，= StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean = 内省）+0 System.Reflection.Assembly.nLoad（AssemblyName 文件名，字符串 = codeBase，证据 assemblySecurity，程序集 locationHint，= StackCrawlMark& stackMark, Boolean throwOnFileNotFound, Boolean = 内省）+43 System.Reflection.Assembly.InternalLoad(AssemblyName assemblyRef, = 证据 assemblySecurity, StackCrawlMark& stackMark, Boolean = 内省）+127 System.Reflection.Assembly.InternalLoad（字符串 assemblyString，= 证据 assemblySecurity, StackCrawlMark& stackMark, Boolean = 内省）+142 System.Reflection.Assembly.Load(String assemblyString) +28 System.Web.Configuration.CompilationSection.LoadAssemblyHelper（字符串 = assemblyName, Boolean starDirective) +46

它让我们发疯。有什么想法吗？

【参考方案1】：

the error you are getting is for a missing unmanaged DLL. 

steps:
1.  See the processors running, if the two are different.
2. Debug your code on the new machine.Step through the code to find where this exception occurs. With that HRESULT, you'll find the exception  where an unmanaged DLL function is called.
3. check the unmanaged DLL.
4. Check if it's there and are referenced correctly. 

还在进程资源管理器中比较两个环境中加载的 dll。
