Attempting to connect via RDP to a Veeam Proxy VM in VMware during a Virtual Appliance (hot-add) backup fails.


This occurs due to hung backup job utilizing that specific proxy, and that proxy is not configured to have automount disabled.


In an Administrator Command Prompt run the following commands:
