JSI Tip 8160. How can I determine if a computer is a member of a specified domain, even If I am logged on locally?

Using NETDOM.EXE and REG.EXE, from the Support / Tools folder of your O/S CD-ROM, or built into your O/S, I have scripted IsDomMbr.bat to determine if the computer you are logged on to is a member of a specified domain.

The syntax for using IsDomMbr.bat is:

IsDomMbr DomainName User Password Answer

Where:

DomainName is the NetBIOS or DNS domain name.
User       is a domain administrator account name.
Password   is the domain password of the User account.
Answer     is a call directed environment variable that will be set to:
              Y - if the computer is a member of the specific DomainName, or 
              N - if the computer is NOT a member.

IsDomMbr.bat contains:

@echo off
if \{%4\}==\{\} @echo Syntax IsDomMbr DomainName User Password Answer&goto :EOF
setlocal
set domain=%1
set user=%2
set pwd=%3
set Answer=N
set nd=netdom query /domain:%domain% /UserD:%user% /PasswordD:%pwd%
set rq=reg query "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion" /v ProductName
for /f "Tokens=2*" %%r in ('%rq%^|find "REG_SZ"') do (
 set pn=%%s
)
set wrk=%pn:server=%
if "%wrk%" EQU "%pn%" goto iswstn
call :netd DC
if "%Answer%" EQU "Y" goto Finish
call :netd SERVER
goto Finish
:iswstn
call :netd WORKSTATION
goto Finish
:netd
for /f "Tokens=*" %%a in ('%nd% %1^|findstr /i /l /c:"%COMPUTERNAME%"') do (
 set Answer=Y
)
goto :EOF
:Finish
endlocal&set %4=%Answer%
