To modify the request Filtering section on BITS-enabled distribution point computers:

Open the applicationHost.config file located in the %windir%\System32\inetsrv\config\ directory on the BITS-enabled distribution point site system.

Search for the <requestFiltering> section.

Determine the file extensions that you will have in the packages on that distribution point. For each file extension that you require, change allowed to true.

For example, if your package will contain a file with an .mdb extension, change the line

<add fileExtension=".mdb" allowed="false" />
 
to

<add fileExtension=".mdb" allowed="true" />

Allow only the file extensions required for your packages.

Save and close the applicationHost.config file.


Now try to map a drive to the the following location on the PILOT-SCCM-01 server.

Right click My Computer > map Network Drive > http://localhost





If webdav fails to work now I would go back uninstall webdav and start again on webdav. Ensure this is fixed now rather than rushing into it ahead as this would cause problems later and make it more difficult to troubleshoot.
