No, I have not solved it. All three of the teams working in our facility are seeing issues, but have worked around it by using static IP addresses. I have a hunch there are many other teams that are having the problem but not reporting it because they have the static IP workaround and we're in a time crunch. I would encourage ANY team that has an issue of mDNS failing to resolve to report the issue.

You can add comments to my reports (search mDNS) or create a new one.
