Whenever I'm doing new installs of Exchange, I'm annoyed when I need to figure out the .NET Framework version installed based on registry keys. You can see the documentation here: https://docs.microsoft.com/en-us/dotnet/framework/migration-guide/how-to-determine-which-versions-are-installed  Just like the bad infomercial says: "There's got to be a better way!"

That file was recreated when the docker service started and I was able to run docker commands.   Running docker network ls showed me that a transparent network I had created
