2. Launch IIS Manager
3. Locate the part of the website (typically the 'Default Web Site') where the Windows authentication has been enabled from.
4. Double-click on the section 'Authentication'
5. Highlight "Windows Authentication"
6. Click "Providers"
7. Modify it so that it contains the correct/relevant providers.
