The authentication works again if we uninstall the security updates, whichever of them that got installed. But KB3193494, as it is a replacement for KB3189866, will automatically be reinstalled again as soon as Windows Update runs again... so it is not a very good workaround.
We do not have any non-domain Windows 7 och 8.1 clients available to test with. Some domain-joined ones are around and then the authentication works.

The server is 1.8.x from a WANDisco distribution, server config says the authentication is set to SSPIAuth, and also should offer basic authentication because of some other clients.

No changes have been made to the server side at all when this problem occurred.

Tried this as a workaround but still get the same authentication error message, the FQDN, user and password was already in the credential manager. Tried removing and reentering info. No success.
