To fix this issue we will have to proceed as follows:

  • Login to the SQL Server host machine.
  • Start “Windows Firewall” application:

Microsoft SQL Server SSIS - The RPC server is unavailable

  • Choose “Inbound Rules” Tab:

Microsoft SQL Server SSIS - The RPC server is unavailable

  • On the right side click on “New Rule“:

Microsoft SQL Server SSIS - The RPC server is unavailable

On the first screen choose “Program“:

Microsoft SQL Server SSIS - The RPC server is unavailable

On Second screen you’d have to search for SSIS executable, usually located at %ProgramFiles%\Microsoft SQL Server\130\DTS\Binn\MsDtsSrvr.exe (in the following case is related to SQL Server 2016):

Microsoft SQL Server SSIS - The RPC server is unavailable

Choose “Allow the Connection“:

Microsoft SQL Server SSIS - The RPC server is unavailable

Uncheck “Public” and if necessary, uncheck “Private” too:

Microsoft SQL Server SSIS - The RPC server is unavailable

Name your new firewall rule and leave some free description for System Administrator and click Finish button:

That is it. Now you can reach and see your SQL Server Integration Service remotely in SQL Server Management Studio:
