Within my environment we currently have a MSSQL installation which serves as the Master in a Multiserver Agent environment (MSX). Due to this server being within a tightly controlled network the necessary ports for MSX functionality have not been opened.
As shown in the image, when I try to enlist a target (TSX) to the master (MSX) I am given an error that the RFC server is not available, I am also unable to deploy multi-server jobs to targets.
What ports should I request to be opened from targets to the master and vice versa?
