c++ dll decompiling

I have an old DLL that stopped working (log2vis.dll) and I want to look inside it to see what objects it uses.
The DLL was written in C++ (not .NET). Is there a tool that will decompile/disassemble C++ files?

This might be impossible or at least very hard. The DLL's contents don't depend (a lot) on it being written in C++; it's all machine code. That code might have been optimized so a lot of information that was present in the original source code is simply gone.

That said, here is one article that goes through a lot of material about doing this.
