How to determine the OS type in a logon script

MORE INFORMATION

Using a simple batch file and a small executable file, you can tell if the client is a:

• Windows 95 or Windows 98 client
• Windows NT workstation
• Windows 2000 Professional installation
• Windows NT Server non-domain controller
• Windows 2000 Server non-domain controller
• Windows NT Server domain controller
• Windows 2000 Server domain controller
• Windows NT Enterprise/Terminal Server domain controller
• Windows NT Enterprise/Terminal Server non-domain controller

Copy the following text to a batch file:

@echo off
REM Batch file to detect OS
REM ----------------------------------
if Windows_NT == %OS% goto WINNT
echo You are not running Windows NT (Windows 95/98 perhaps?)
goto END

:WINNT
gettype.exe

if errorlevel=9 goto FILENOTFOUND

echo You are running Windows NT.
echo More Specifically:
echo.


if ERRORLEVEL=8 goto EIGHT
if ERRORLEVEL=7 goto SEVEN
if ERRORLEVEL=6 goto SIX
if ERRORLEVEL=5 goto FIVE
if ERRORLEVEL=4 goto FOUR
if ERRORLEVEL=3 goto THREE
if ERRORLEVEL=2 goto TWO
if ERRORLEVEL=1 goto ONE

:FILENOTFOUND
echo.
echo Gettype not found.
echo.
goto END

:EIGHT
echo Windows NT Enterprise/Terminal Server Non-Domain Controller
goto END

:SEVEN
echo Windows NT Enterprise/Terminal Server Domain Controller
goto END

:SIX
echo Windows 2000 Server Domain Controller
goto END

:FIVE
echo Windows NT Server Domain Controller
goto END

:FOUR
echo Windows 2000 Server Non-Domain Controller
goto END

:THREE

Copy the Gettype.exe file and the batch file to the target workstations and run the batch file.

You can obtain Gettype.exe version 4.0 by installing the Windows 2000 Resource Kit Tools.
Gettype.exe works by querying the registry for the installation type and setting the DOS ERRORLEVEL appropriately:

• Returns 1 for Windows NT Workstation.
• Returns 2 for Windows 2000 Professional.
• Returns 3 for Windows NT Server non-domain controller.
• Returns 4 for Windows 2000 Server non-domain controller.
• Returns 5 for Windows NT Server domain controller.
• Returns 6 for Windows 2000 Server domain controller.
• Returns 7 for Windows NT Enterprise/Terminal Server domain controller.
• Returns 8 for Windows NT Enterprise/Terminal Server non-domain controller.

Silent mode can be set with the /s parameter. This tool can also be run against remote computers.
