11111 » How can a batch retrieve the full DNS name of the current computer? (19-Dec-06)

Using standard commands, I have scripted FullDNSName.bat to retrieve the full DNS name of the current computer.

The syntax for using FullDNSName.bat is:

[call] FullDNSName Name

Where Name is a call directed environment variable that will contain the computer's full DNS name.

FullDNSName.bat contains:

@echo off
if {%1}=={} @echo Syntax: FullDNSName Name&goto :EOF
if exist "%TEMP%\FullDNSName.vbs" goto doit
@echo.Set objSysInfo = CreateObject("ADSystemInfo") >"%TEMP%\FullDNSName.vbs"
@echo.strComputerDN = objSysInfo.ComputerName>>"%TEMP%\FullDNSName.vbs"
@echo.Set objComputer = GetObject("LDAP://" ^& strComputerDN)>>"%TEMP%\FullDNSName.vbs"
@echo.Wscript.Echo objComputer.dnsHostName>>"%TEMP%\FullDNSName.vbs"
:doit
set %1=Not Found
for /f "Tokens=*" %%a in ('cscript //nologo "%TEMP%\FullDNSName.vbs"') do (
 set %1=%%a
)
