[Boost-users] Re: Running boost::thread compiled on w2k on XP

You may want to try running the dependency checker on the dll. Perhaps 
you have different versions of libraries being loaded. If you have MSVC, 
just run depends.exe. Otherwise, you can download this useful tool from 
the author at http://www.dependencywalker.com/.

We too have built boost threads dll on Windows 2000 and successfully 
used it on Windows XP.
