We are starting to work with Tableau 8 data sources and we are encountering problems with an error when attempting to connect to published data sources. The error appears to appear primarily for the person who created the data sources. Other uses may be able to connect to the data source.
The error is somewhat random, but seems to occur consistently for the person who publishes the data source, while other users often can connect to and use the data source.
Our server administrator is not seeing a problem on the Tableau server.
Content of Error message:
Fatal exception in native C++ engine

Try changing the Tableau Server Run-As Account to be a real Windows user who has read/write capabilities on that machine. For testing purposes you can even change it to your Windows account (even beyond for testing, you can leave it as your account). Keep in mind that if you use MS SQL Server, this account must also have access to that database as well.
To change the run-as account, remote into the server machine, stop tableau server, and then go to 'Configure Tableau Server' and change it there. Then save, and start the server again.
I just tried this and it fixed the same issue on the server I was working with, but may not be the same issue you are experiencing.
