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
