RPC Server Unavailable (0x800706BA) from MID Server

[imtiazahmad]

• We are receiving the 0x800706BA – RPC Server Unavailable error from the MID Server while attempting to connect to the host machine.
• We have already verified that the required permissions are in place, the necessary services are running on the host, and the relevant firewall rules are configured correctly. However, the MID Server is still unable to establish the RPC connection with the host.
• Could you please assist us in identifying any additional configuration or connectivity checks that we should perform?

I'm not entirely sure, but I believe I covered this in my training.

Did you start the required service for this? If not, please check that first, as it could be the reason for the issue.

Yes, the required services are already running on both the source and host machines. We have also verified that TNC to RPC port 135 is successful. However, we are still encountering the RPC Server Unavailable (0x800706BA) error.
