After configuring Bold BI, stop the default site, go to the Bold BI Enterprise Edition site bindings in the IIS manager, remove the localhost, and put 80 in the port. 4. Install or deploy Bold BI in other remaining N-1 machines and point to 80 port. However, we should not do any startup configuration in these machines and copy the configuration folder from the default installation location installeddrive\BoldServices\app_data in machine 1 and replace it in the other machines in the same location. 5. Restart your sites in the IIS manager for the files replaced machines and open Bold BI in a private window and Verify the setup works properly by adding a resource.
