Summary

Reference this Microsoft MSDN article.

Details

1. Check the Security Token Service log on the server
   
   • The following error will appear in the log:
     • The service failed to start: System.ServiceModel.AddressAccessDeniedException: HTTP could not register URL http://+:8020/wgv.services/. Your process does not have access rights to this namespace (see http://go.microsoft.com/fwlink/?LinkId=70353 for details). ---> System.Net.HttpListenerException: Access is denied
2. Check that all certificates are valid
3. Make sure to log into the server as a local administrator
4. Make sure nothing else has changed that would cause a network connectivity problem
5. If the Security Token Service is running but you are still unable to log in, open a command prompt window as an administrator and enter:
   • netsh http add urlacl url=http://+:8020/wgv.services/ user=”NT AUTHORITY\NETWORK SERVICE"
   • This command enters the URL namespace back in the program
