I had encountered the same error "Microsoft SQL: The target principal name is incorrect. Cannot generate SSPI context." when trying to refresh data on PBI Desktop. 

 

Before the error showed up, PBI Desktop could connect to the SQL DB and refresh data for the past 18 months. The error msg just showed up one day.

 

The SQL DB's Windows server password had expired. However, that password remains unchanged as per company policy. 

 

The following steps help to resolve my issue:

  1. Go to Power Query Editor window
  2. Click on "Data Source Settings" from the ribbon menu
  3. In the "Data Source Settings" window, select the affected data source and click on "Edit Permissions"
  4. In the "Edit Permissions" window, under "Credentials", click on "Edit".
  5. Select "Database" and fill up the SQL credentials.
  6. Save and refresh all data.

Thank you so much, it worked well for me.

 

Thank you so much! I thought it was just enough to change the Server Name and Database Name. Upon going to this part of the settings and refreshing the Database's Username and Password, it worked like a charm! Once again, thank you so much!

Exellent answer. Power BI is fantastic but the UI is a complete dogs breakfast now

hi, @Anonymous 

This is an issue about SQL SERVER. There could be many causes. You can reference these two posts. It would be good idea to post in  SQL Server Security Forum for assistance.

Can you connect to this SQL Server instance using ANY OTHER Tools? such as SSMS (SQL Server Management Studio) or something else?

This might be the case that the connection services for SQL Server are not configured properly. SQL Browser is not running, and many other reasons why the connection to SQL Server is not working.
