You could just script the action and log it each time. Problem is, if your people are smart they could go in and edit the logs, but if they were smart they wouldn't be abusing a remoting software. And if they do prove to be smart, instead of writing the information to a log you could code it to e-mail you each time they use it.
remotecontrol.vbs {computer}
If WScript.Arguments.Count = 1 Then
'Bring in target computer name
strRemoteComputer= WScript.Arguments(0)
'Grab the data and time of calling the script
strDate = Date()
strTime = Time()
strComputer = "."
Dim WshShell
Dim objFSO
Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set WshShell = WScript.CreateObject ("WSCript.shell")
Set objFSO= CreateObject("Scripting.FileSystemObject")
Set objText = objFSO.OpenTextFile("\\LansweeperServer\LansweeperShare$\logs\lsremotelog.txt", 8, True)
Set colItems = objWMIService.ExecQuery("Select * From Win32_ComputerSystem")
'Find the username of the person clicking the link
For Each objItem in colItems
strUser = objItem.UserName
Next
'Write the log entry with Date, Time, User, and Target PC
objText.WriteLine(strDate & " " & strTime & " " & strUser & " " & strRemoteComputer)
objText.Close
'Run your command
WshShell.run("\\LansweeperServer\LansweeperShare$\lsremote.exe " & strRemoteComputer)
End If

P.S. Change file paths to something that actually works, and note that the lansweeper share isn't writable so you may want to put the log folder somewhere else.
