I have a mindmp file from a target\'s application crash. Is it possible for me to rebuild the dll/pdb files for a version of software and have windbg load symbols correctly?
In my experience probably not.
If you have the exact build directory and build with the exact same compiler settings then this might work. You definitely will not be able to load symbols from a debug build against a release crash dump.
You will need to turn on the 'load anything' options: .symopt+0x40 to get windbg to ignore the timestamp differences.
