You are a Power BI administrator. A user reports that their scheduled data refresh fails with error 'The data source credentials are no longer valid.' The dataset uses a SQL Server database with Windows authentication. What should you do first to resolve the issue?
Windows credentials may expire; updating them in the service resolves the error.
Why this answer
The error 'The data source credentials are no longer valid' typically occurs when the password has changed or expired. The user can update the credentials in the dataset settings in the Power BI service. Option A is incorrect because the on-premises data gateway is not the issue; a reinstall is unnecessary.
Option B is incorrect because reassigning the dataset to a different Premium capacity does not address credential validity. Option C is incorrect because using 'Impersonate the authenticated user' still requires valid credentials and does not fix the problem.
