You are not authorized to view this page due to invalid authentication headers


When you attempt to access a web application in IIS such as XIA Configuration Server, you receive the following message:

HTTP Error 401.2 - Unauthorized
You are not authorized to view this page due to invalid authentication headers.


This can be caused by incorrect configuration of the Windows Authentication settings in IIS.


To resolve the issue, browse to the web application in IIS, go to Authentication and ensure Windows Authentication is enabled.

Next, with Windows Authentication selected, press 'Providers...' in the right hand Actions pane, then check that both Negotiate and NTLM are present.

Location is not accessible - C:\ is not accessible - Access is denied.

This post describes one way to fix the error "Location is not accessible - C:\ is not accessible - Access is denied."

This can be frustrating as the C:\ drive can't be accessed!

The cause of this issue in my case was because a user had been created in local users and groups with a home folder connected to \\localhost\c$.  This changed the security of the C:\ drive to only allow access to that user and Administrators.


1. Right click the C:\ drive and select Properties then go to the Security tab, press Advanced then Continue to open Advanced Security Settings

2. Now press Add then the 'Select a principal' hyperlink

3. Change the Location to the local machine if necessary, then type Users, Check Names and press OK

4. Press OK, then OK, then Yes in the Windows Security dialog box

Windows will now set the security information.  Click the Windows Security box to check the progress - you may see some errors setting the security on subfolders, these can be ignored by pressing Continue.

All Users should now have read access to the C:\ drive
