I too just had this same issue and wanted to share my results as it seemed to be common. Basically my symptom was that my remote DP's were receiving content fine, however none of the clients assigned to use those DP's via boundaries were allowing content to download, specifically software updates. After searching for days and days and trying all of the tricks i could find such as enabling anonymous authentication on the DP’s, recreating the deployments, etc., i traced the issue down to IIS. All of my clients pointing to these remote DP’s were getting the following errors, “Successfully sent location services HTTP failure message” “Error sending DAV requests. HTTP code 500, status internal server error” “Non-recoverable error retrieving manifest 0x87d0027e”Long story short BITS and ASP.net were not installed on my remote DP's. I had followed the pre-req check and chose the option to automatically install/configure IIS when setting up the DP’s, and looked at logs and didn’t have any issues, also i cannot find any Microsoft documentation that explicitly lists these as requirements for distribution points. However, as soon as i installed these components and rebooted this resolved my issue on all 3 of my remote DP's. Hope this helps some people out there who struggled with this issue as much as I did. I'm aware that these components are required for your CAS and/or Primary Site Server which is explains why clients pointed to it as a DP were working fine, but apparently the same pre-reqs required to install Primary Site Server are also required for DP's.
