I used to work as a senior technical support for BEA Weblogic and had all sorts of crazy situations to debug remotely. Including one time when I had to get a person to edit a config file in Vim (which they never used before), on Unix (which they never used before), with me guiding them by phone (no visuals).
And if somebody really understands network and multicast, I would love to know whether I actually nailed the problem or just made it go away accidentally. I have no problems with being wrong, especially this much later :-)

This is the one I recorded that seems to fit into the current theme: https://www.outerthoughts.com/2004/10/perfect-multicast-stor... (tldr: multicasting on 237.0.0.1 is bad).
