Setting Up the Server for Uploads

To upload files to a server using BITS, the server must have IIS and the BITS server extension ISAPI installed. For IIS requirements, see IIS Requirements for BITS Uploads.

For information on configuring the IIS virtual directory that BITS uses for uploads, see the following topics.


Some IIS installations include the UrlScan filtering component. If UrlScan is enabled, the administrator must add the "BITS_POST" verb to UrlScan's list of allowed HTTP verbs. Otherwise, BITS client uploads will fail. For further details on enabling verbs in UrlScan, see the UrlScan documentation.
