When using Vista or Windows 2008 or above, you find you are prompted for a password by the browser even though the system is configured with Windows Authentication.

Clicking cancel displays an Unauthorized error message.

This is caused by the local server not being in your Intranet Zone and therefore the browser is not passing your current credentials to the XIA Automation Server.


  • Add the XIA Automation Server URL to your Intranet Zone in Internet Options

  • Ensure that access to the XIA Automation Server is not being routed via a proxy server.

  • When using the Firefox web browser, please see the following article Using Integrated Authentication with Firefox.
