When Windows NT or Windows 2000 is installed, %SystemRoot%\System32\$winnt%.inf is created. If you inspect the \[data\] section, using notepad, you can determine how the operating system was installed. Here is a sample $winnt$.inf file:
\[setupparams\] skipmissingfiles = "0" \[data\] unattendedinstall = "no" floppylessbootpath = "no" producttype = "winnt" standardserverupgrade = "no" winntupgrade = "no" win9xupgrade = "no" win31upgrade = "no" sourcepath = "\device\cdrom0\" floppyless = "0" msdosinitiated = "0" dospath=D:\If all the parameters than end in upgrade are "no", the OS was a clean installation on a partion that had no existing operating system.
NOTE: If you subsequently perform an update install, winntupgrade may toggle to "yes".
Here is a sample Windows 2000 script, that uses NETDOM from the Support Tools, to query all member workstations.
The report is displayed on the console and written to %tmp%\upgrade.txt.
@echo off setlocal for /f "Tokens=*" %%i in ('date /t') do set dte=%%i for /f "Tokens=*" %%i in ('time /t') do set tme=%%i @echo %dte% %tme% @echo %dte% %tme% >%tmp%\upgrade.txt for /f "Skip=1 Tokens=1,2" %%i in ('netdom query workstation') do call :mbr %%i %%j endlocal goto end :mbr if "%1"
"The" goto done1 :mbr1 set cname=%1 if not exist \\%cname%\c$\winnt\system32\$winnt$.inf goto end set dp=N for /f "Skip=3 Tokens=*" %%i in (\\%cname%\c$\winnt\system32\$winnt$.inf) do call :parse "%%i" goto end :done1 if "%2""command" goto end goto mbr1 :parse if "%dp%"
