The Great PowerPivot FAQ: Troubleshoot error "The data connection uses windows authentication and user credentials could not be delegated"

Title

Troubleshoot error "The data connection uses windows authentication and user credentials could not be delegated" 

Answer

The easier solution is if the Microsoft "Geneva" Claims to Windows Token Service is not running on the machine. Start this service from the services control panel
 
If this isn't the case, the problem might be more serious involving domain configuration and connection to domain issues. Dave's blog talks about this scenario - http://powerpivotgeek.com/2009/11/06/taking-your-server-off-the-network/

Resolvendo o erro: "A conexão de dados usa autenticação windows e as credenciais não podem ser delegadas" ("The data connection uses windows authentication and user credentials could not be delegated") 

Resposta

A solução mais fácil é se o Microsoft "Geneva" diz que o Windows Token Service não está rodando na máquina. Inicie o serviço através do painel de controle de serviços.
 
Se este não for o caso, o problema pode ser mais sério e envolver tópicos de configuração e conexão ao domínio. O blog do Dave relata sobre este cenário: http://powerpivotgeek.com/2009/11/06/taking-your-server-off-the-network/
