[MacTUG] Microsoft Remote Desktop 10

[Mike Patterson]

For what it's worth, I was unable to reproduce the ARPing behaviour, but I only tried once. I ran tcpdump after closing most things, opened Remote Desktop, connected to a system, closed RD. MSRD version 10.2.2 build 1291.

Version 8 worked fine, but version 10 was incompatible with our security standards for network ports (ARP rate limiting, to be specific). At the time, we decided that the workaround of using version 8 was a better path forward than loosening security controls.
