I have the same problem with a user
stopping the host and ran across this post looking for a solution.
While looking into some of the many free File & Folder Hide/Lock programs, it dawned on me that just removing "stop" in the target field of the shortcut to the Stop Host icon found in Start/All Programs/Remote Utilities - Host folder might work and trivial to add again if needed by the Admin.
"C:\Program Files (x86)\Remote Utilities - Host\rutserv.exe" /
stop
