The information in this article applies to:

- Microsoft Windows NT Server versions 3.51, 4.0 
- Microsoft Windows NT Workstation versions 3.51, 4.0 
- Microsoft Windows NT Server, Enterprise Edition version 4.0 
- Microsoft Windows NT Server version 4.0, Terminal Server Edition 
- Microsoft Windows 98 
- Microsoft Windows 95 
-------------------------------------------------------------------------------

SUMMARY
=======

Often, administrators would like to run software on only their Windows 95 or
Windows 98 clients, or their Windows NT Workstation clients. They may not want
to run some logon script commands on their Windows NT Server computers or domain
controllers.

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
  echo Windows NT Server Non-Domain Controller
  goto END

  :TWO
  echo Windows 2000 Professional installation
  goto END

  :ONE
  echo Windows NT Workstation
  goto END

  :END
  pause

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 from 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.
