Error Code: 8009030e
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.
Properly configure your environment for Kerberos authentication. Please visit Microsoft's website for further information regarding how this can be done.
In the Internet Information Services console, expand down to the web interface site you wish to configure.
