IIS Authentication and Access Control Diagnostics Tool

This came in handy debugging the shonky install for the ESB Toolkit 2

Authentication and Access Control Diagnostics 1.0 (x86)

I was getting an error in the event log;

“The remote server returned an error: (401) Unauthorized”

The tool pointed me at the ESB.Exceptions.Service virtual directory.  Loading the .svc file in here directly led me to change the authentication provider to “Negotiate,NTLM”

C:\Inetpub\AdminScripts>cscript adsutil.vbs set w3svc/NTAuthenticationProviders
"Negotiate,NTLM"
