WinDbgが発する「Failed to load data access DLL, 0x80004005」を無理やり回避した方法

方針：

• 欲しい mscordacwks.dll が無いと言っているので、欲しくない mscordacwks.dll で代用してみます。

手順：

1. [File]→[Symbol File Path...] にて、正しいパスを設定しているかどうかを確認します。
   
   例：
   cache*C:\DL.Symbols;SRV*http://msdl.microsoft.com/download/symbols
   
   C:\DL.Symbolsは、正しいシンボルファイル置き場に書き換えてください。
   
   Symbol File Pathを書き換える時は、WinDbgの起動直後にするのが良いです。
   
   また、何回も設定・終了・起動をして見て、きちんと書き換えられているかどうか、確認するのが良いです。
    
2.  [File]→[Open Crash Dump...]で、開きます。
    
3. .load C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\sos.dll

   Verify that 1) you have a recent build of the debugger (6.2.14 or newer)
               2) the file mscordacwks.dll that matches your version of mscorwks.dll is 
                   in the version directory
               3) or, if you are debugging a dump file, verify that the file 
                   mscordacwks___.dll is on your symbol path.
               4) you are debugging on the same architecture as the dump file.
                   For example, an IA64 dump file must be debugged on an IA64
                   machine.

   Verify that 1) you have a recent build of the debugger (6.2.14 or newer)
               2) the file mscordacwks.dll that matches your version of mscorwks.dll is 
                   in the version directory
               3) or, if you are debugging a dump file, verify that the file 
                   mscordacwks___.dll is on your symbol path.
               4) you are debugging on the same architecture as the dump file.
                   For example, an IA64 dump file must be debugged on an IA64
                   machine.
   You can also run the debugger command .cordll to control the debugger's
   load of mscordacwks.dll.  .cordll -ve -u -l will do a verbose reload.
   If that succeeds, the SOS command should work on retry.
   If you are debugging a minidump, you need to make sure that your executable
   path is pointing to mscorwks.dll as well.

   COPY C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscordacwks.dll C:\DL.Symbo
   ls\mscorwks.dll\4E154C985a9000\mscordacwks.dll
           1 個のファイルをコピーしました。
