JSI Tip 2476. How do I script an install, execution, and removal of the Remote Command Service?

In tip 1951 - "How do I install the Remote Command Service, remotely?",
I used tools from the Server Resource Kit and Supplement 4, to remotely install the Remote Command Service.

David A. Stewart, MCSE - Systems Administrator/RL-ATD/Eastman Kodak Co. - [email protected]
has provided a method to install, execute, and remove the service,
if you have security concerns with leaving it in place.

OpenRCMD.BAT uses Sc.exe, Rcmd.exe, Rcmdsvc.exe, and Oemnsvrc.inf
from the Server Resource Kit and Supplement 4.

Usage: OpenRCMD

where ComputerName is the NetBIOS name of the remote computer.

OpenRCMD.BAT contains:

@ECHO OFF
cls
If \{%1\}==\{\} @echo computer name is required.&goto verybottom
set computer=%1
if not exist \\%computer%\admin$\system32\*.* @echo computer name is invalid or unavailable&goto verybottom
REM *** Display current variable settings ***
echo.
echo Current Computer is %computer%.
echo.
REM Install and start the Remote Command Server
set error=none
echo.
set tempa=
set rsystemroot=
FOR /F "skip=1 delims=    tokens=1-3" %%a in ('reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRoot" \\%computer%') do set tempa=%%c
FOR /F "tokens=1" %%a in ('@echo %tempa%') do set rsystemroot=%%a
