Would like to how do you do it. I'm not sure if we can do that. If so can you please let me know the process of how to connect it from tableau desktop local machine to RDC sql server
while connecting to SQL server from Tableau you should give the IP address of the machine or server name or DNS name. Give your userid and password it should allow you to connect.
Best example is : We have a Tableau repository database in a Virtual machine and we were able to connect it from our local system correct..same way..you can do for SQL server as well.
Try and let us know for any questions.
