DOCUMENT:Q190899 22-MAY-2002 [crossnet] TITLE :How to Determine the OS Type in a Logon Script PRODUCT :Windows for Workgroups and Windows NT Networking Issues PROD/VER::3.51,4.0 OPER/SYS: KEYWORDS:kbenv ====================================================================== ------------------------------------------------------------------------------- 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.
