Erro ao criar novo Team project

[Javerson Santana]

Boa tarde a todos.

Gostaria de solicitar a ajuda de todos mais uma vez.

Ontem fui criar um novo Team Project, porém ao finalizar a criação surgiu a seguinte mensagem de erro.

TF218027: The following reporting folder could not be created on the server reporting services: /TfsReports/Empresa.

The report server cannot decrypt the symmetric key that is used to access sensitive or encrypted data in a report server database. You must either restore a backup key or delete all emcrypted content.. verify that the path is correct and thar you have sifficient permissions to create a folder on that server, and then try again.

Estou desde ontem realizando processos que vejo na internet para resolver esse problema, mais ate o momento não esta dando certo.

Alguém teria alguma solução?

Obrigado.

o you happen to have a backup of your encryption key?  If not, follow these steps: 

Open Reporting Services Configuration Manager

Connect to your RS server

Select 'Encryption Keys' from the left pane

Press the 'Delete' button to get rid of your encrypted content 

After doing this, you will need to re-set the connection strings and stored credentials on your reports. 

Also, I'd be sure to make a backup of the encryption key afterwards.

 If you do have a backup, press the 'Restore' button instead of the 'Delete' button.

 Hope this helps.

Do not forget to go in to SCCM -> Administration -> Accounts   and re-enter the credentials for the account you use to query SQL or it will not work properly.

Obrigado a todos.
