Script for dumping DHCP subnet scope options

Here’s simple script I’ve put together as I was in need of one that dumps the DHCP subnet scope options into a text file.

The script first queries the DHCP servers it can find and then dumps the scope options of each subnet it finds on each DHCP server.

Copy the below code and save it as dhcpsubnetscopeoptions.cmd

@echo off

echo %date% %time% >%~dp0\dhcpsubnetscopeoptions.txt

echo —————————————————————– >>%~dp0\dhcpscopeoptions.txt

Echo Dumping DHCP Subnet Scope options

for /f "skip=2 tokens=4 delims=[] " %%G in (‘netsh.exe dhcp show server’) DO (call :sub1 %%G)


set srv=%1

for /f "skip=4 tokens=1 delims= " %%a in (‘netsh.exe dhcp server %srv% show scope’) DO (

IF "%%a" == "Total" (echo.

) ELSE IF "%%a" == "Command" (echo.

) ELSE (netsh dhcp server %srv% scope %%a show optionvalue >>%~dp0\dhcpsubnetscopeoptions.txt



Note that you must have appropriate rights such as DHCP Users, DHCP Administrators or Domain admin to retrieve the information. The output is saved into a file called dhcpsubnetoptions.txt

The script has been tested on Windows 7 against a Windows 2008 DHCP Server.
