When using Intelligence Agent with a server endpoint, this error may be present in the error log:
Hubstream.Intelligence.Agent.exe Error: 0 : Error occured in download agent. The HTTP request is unauthorized with client authentication scheme 'Negotiate'. The authentication header received from the server was 'Negotiate,NTLM'.
This error may be masking a user credentials issue. To resolve:
- In Agent settings, check that the user name and password are correctly entered and retry
- Administrators - check that the user account is set up in the appropriate Active Directory groups and as an Intelligence Server user.
If you have verified that the user credentials and group membership are correct, the next option is to use WCF tracing as described in Troubleshoot network issues with Intelligence Agent
