It appears that I did not get my point across.
MsiFiler.exe can be used on MSI file to populate File table and MsiFileHash table, it does not, however, stream files into MSI file. The error occurs at build time, while MSI file is being built. MsiFiler.exe can only be used after MSI file is built, hence, it is not the right tool to resolve the error.
From the error message, it indicates files captured by Repackager are located on I drive. While building MSI file, DevStudio has to access I drive for files included in ISM (which is what I meant by
building MSI across network). In this setting, network congestions could have caused -6271 error, while there is nothing wrong in ISM. As I suggested in my earlier post, if the error occurs on a more regular basis due network congestions, it is advised to keep files captured and MSI built on your local machine. By doing this, we can eliminate network congestions as a possible culprit.
