Information on Running Sample Files with IIS Some of the samples on the companion CD use IIS virtual directories, which must be mapped to the hard disk in the normal directory structure (not the Documents directory) for it to run successfully. Installing the sample tree in the normal directory structure violates Microsoft's security standards. To run the samples through IIS, copy the samples files to a directory somewhere other than c:Documents and map an IIS Virtual directory to the sample tree
