I would try it at the site level first, Run with elevated permission i.e. Run as Administrator
Enable directory browsing at the site level
cd "C:\Program Files (x86)\IIS Express\"
run this appcmd.exe set config "Contoso Some SITE NAME" -section:system.webServer/directoryBrowse /enabled:"True" /showFlags:"Date, Time, Size, Extension"
check to turn off encryption and read only in folder options
Note: Run with elevated permission
GUI version from Microsoft site for other versions:
- On the Start screen, move the pointer all the way to the lower left
corner, right-click the Start button, and then click Control Panel.
- In Control Panel, click Programs and Features, and then click Turn
Windows features on or off.
- Expand Internet Information Services,
expand World Wide Web Services, expand Common HTTP Features, and
then select Directory Browsing.
Click OK.
Click Close.
If it still does not work, then try & delete all the IIS cache and repeat the above
I previously answered this, and it works well here for the majority of people
Open CMD prompt & Navigate to IIS express - by typing the following
cd "C:\Program Files (x86)\IIS Express\"
run this appcmd.exe list site /xml | appcmd delete site /in
This will delete all the sites, enjoy!
