Expression Encoder may show error when publishing large file to WebDav


  • You are using Expression Encoder to encode video with a Transcode Project.
  • You are publishing the video using WebDAV.
  • The encoded video is larger than 30 Mbytes.
Expression Encoder may show an error - "A WebDav publishing error occurred: the remote server returned an error: (404) Not Found”.


There is a default maximum size limit for WebDAV uploads on the IIS server. The limit is 30 MBytes.  


On the IIS server use Notepad to open the Web application configuration file Web.config. By default, this file is in the following folder:

Increase the value of maxAllowedContentLength in the requestLimits node. For example: <requestLimits maxAllowedContentLength="52428800"/>

Note: If your Web.config file does not already have the <requestLimits> node, you must add it in the proper place in the section hierarchy, which follows this structure:

<requestLimits maxAllowedContentLength="52428800"/>
