This has nothing to do with Cygwin, it's a 64-bit Windows limitation. Certain files in a 64-bit system are implicitely hidden from accessing them from the WOW64 32-bit environment. In the 64-bit version of cmd.exe, the system32/inetsrv directory has 82 files and directories when calling `dir /w'. If you do the same in a 32 bit cmd.exe(*), you can only see 60 files and directories. Why? The reason for this is that 32-bit processes are internally redirected to different directories under some circumstances. The WINDOWS/system32 directory is one of these cases. If an application running under WOW64 chdir's to C:\WINDOWS\system32, it is actually redirected to the directory C:\WINDOWS\SysWOW64. If you examine the C:\WINDOWS\SysWOW64\inetsrv directory with the 64-bit cmd.exe, you will find that it contains 60 files and directories. That's it. As for having a workaround, I know the system call to switch off this redirection per thread, but I'm not convinced that it would be a good idea to use it for Cygwin processes. After all, Cygwin processes are 32-bit processes and should see the same environment as any native 32-bit process.
