IIS 405 PUT Method Not Allowed in IIS Manager

By | May 23, 2013

In this blog, we will discuss about SDATA PUT method that is supported by Sage 300 (formerly Sage Accpac ERP) PORTAL, but it’s not allowed as default in IIS manager.

PUT is considered as WebDAV verb, and WebDAV module claims the request, but it returns 405 since WebDAV is disabled.

WebDAV cannot be set with other module like RESTFull, also handling WebDAV specific verb, such as PUT, DELETE, COPY, etc. Disable WebDAV on site does not resolve your concern.

Hence, to allow IIS to support PUT method; we will have to make following changes in IIS manager.

  • If OS is Vista or W2K8, then navigate to control panel/Add Remove Program, and remove WebDAV.
  • If OS is Win7 or server machine, then navigate to Server Manager >> Role >> Web Server -> Common HTTP Features -> WebDAV Publishing, and for client machine  Control Panel -> Uninstall Program -> Turn Windows features on or off -> IIS -> World Wide Web Services -> Common HTTP feature -> WebDAV Publishing.

A simple one-step solution to resolve issue is to uninstall WebDAV module, to handle 405 error in IIS Manager.
