ITCM  wac  login fails  -  HTTP Error 404.7   FILE_EXTENSION_DENIED

 

This can caused by IIS not allowing unlisted extension to run.

Client removed ‘allow unlisted file name ext  and allow high bit character ‘ and then  use ‘allow file name extension’  filter.

 

They had  .CSS, .ENU ,.HTM, .HTML,. JS, .JSP,  .PHP, filtered for other product .  

 

But  itcm  wac  login fails  -  HTTP Error 404.7   FILE_EXTENSION_DENIED

 

WAC uses CSS and .gif .png files. Therefore we need to add .gif and .png ( including 'xml') to the allowed extension .

 

Though Microsoft resolution for  HTTP Error 404.7   FILE_EXTENSION_DENIED  is as follows:

 

To allow unlisted extension to run:

 

1>Open File Explorer and go to %windir%\System32\inetsrv\config

 

2>Create a backup copy of applicationHost.config

 

3>Edit the applicationHost.config

 

4>Search for <requestFiltering> section

 

5>Change <fileExtension allowUnlisted="false"> to <fileExtension allowUnlisted="true">

 

6>Save and restart IIS services

 

WebAdmin  console should now be accessible
