Title
Web Interface error 401.1 Unauthorized Error Code 8009030e -
Description
When trying to log into the Web Interface, you receive: HTTP Error 401.1 - Unauthorized: Access is denied due to invalid credentials
Error Code: 8009030e
-
Cause
The Authentication Provider in IIS is set to Negotiate and Kerberos authentication is not configured properly.
Negotiate Authentication Provider selects between Kerberos authentication or NTLM authentication types. It will select Kerberos first. Sometimes if Kerberos is not configured properly, instead of switching to NTLM, it will throw the 401.1 Unauthorized error instead.

Workaround 2
In the Internet Information Services console, expand down to the web interface site you wish to configure.

- Double-click Authentication
- Click Providers on the right pane
- Select NTLM and click Move Up
- Click Ok
