This can happen when your website is configured to accept Window Integrated Authentication only (which is correct) but the browser is not.
To resolve this issue:
1 In your browser, go to Tools > Internet Options > Security > Local Intranet > Custom Level > User Authentication.
This assumes System Architect XT is on the local intranet.
2 Review the following settings to identify and to resolve the error:
If Anonymous Login is checked.
Ensure that Automatic Login only in intranet zone is checked.
