Wscript.shell Run Command Not Work Prope

Hello .
this is old Topic but I have problem Exist.
i tried to Debug Problem As this ways
First :
Kill.exe When You Pass it hostName and User ID it Will Kill User From RAS
Like : Kill.exe 127.0.0.1 Cafe123
1- i run Command(CMD) from Run Menu and inside it Tried This
 d:\wwwroot\Kill.exe 127.0.0.1 Cafe20
 and resault(output) is Like This
  cafe10
  cafe13
  Cafe16
  New23
  cafe20 -x-
  ...
Then This User Was Disconnected From Ras
if User Dos not Exist Above list Will show but Without -x-
this is Good .
now I try this
d:\wwwroot\kill.exe 127.0.0.1 cafe20 >> d:\wwwroot\kill.txt
bomb... this File Created and Have above Resault inside
now i exit Command env....
in My Script i tried This :

Set Shell = Server.CreateObject("Wscript.Shell")
Shell.Run "CMD /c Dir c:\ >> d:\wwwroot\kill.txt"

Set Shell = Server.CreateObject("Wscript.Shell")
  strKilluser = Server.MapPath("execute\Kill.exe")
  strKilluser = "CMD /c "&strKilluser & " 127.0.0.1 " & user &" >> d:\wwwroot\kill.txt"
  Shell.Run strKilluser

And This Changed Lines

strKillUser = "CMD /c d:\wwwroot\kill.exe 127.0.0.1 test >> d:\wwwroot\kill.txt"

strKillUser ="CMD /c ""d:\wwwroot\kill.exe 127.0.0.1 test >> d:\wwwroot\kill.txt"""
