Tracking Common DLLs among several applications

I have several vb.net common code libraries that are used throughout
multiple applications in our enterprise. For example, we have code
libraries to handle logging, error handling, database connections,
standard UI components, etc. These are used in almost all of our
desktop applications. Over the past month, it has become a nightmare
to try and manually keep track of what applications are using these
common dlls. Whenever we update one of the common libraries, we want
to make sure the new dll is copied to the bin directory of the
applications using them. Does anyone have any suggestions for methods
or even applications that will track where dll's are deployed and can
make this process easier?

Thanks for the help
