If you install Windows Resource Kit or Visual C++ 6.0, then you'll have installed the Dependency Walker (or Depends) program, which is a great tool to inspect what's inside a DLL.

Another great tool is dumpbin.exe, which is installed with VC++. It is a command line program, but it extracts a lot of info from a dll.
