IIS installation problem with XP SP2
Having problem installing IIS with SP2? Keep getting file not found dialog box? No matter, which source installation CD or path you browse to, the system still claims that it can't copy the file? Well, try this new KB.
You may receive the "Setup cannot copy the file staxmem.dll" error message when you try to install IIS on a computer that is running Windows XP Professional with SP2
