I am updating out DHCP config and wrote this script to get the MAC address of a remote computer on the network. It works fine if I leave the errorlevel part out of it, but I want the errorlevel included so it ECHO's that the host was not found, if it wasn't found. I just can't seem to get it to work. Does ping.exe have errorlevels? Here's the script: :start cls @echo off title getMAC echo Clearing ARP Cache . . . netsh interface ip delete arpcache echo Enter IP address of remote computer: set /p ip= for %%i in (%ip%) do ping -n 1 %%i cls if %errorlevel% == 1 ( goto fail ) else ( arp -a | findstr "%%i" ) :fail echo Host not found, or not alive . . . pause goto start cls No matter what, it always ECHO's Host not found, or not alive . . . and doesn't output anything else. The MAC and IP address should be displayed on stdout. In the script below it :start cls @echo off title getMAC echo Clearing ARP Cache . . . netsh interface ip delete arpcache echo Enter IP address of remote computer: set /p ip= for %%i in (%ip%) do (ping -n 1 %%i cls arp -a | findstr "%%i" ) pause goto start cls The above script works exactly as it is suppossed to. What's wrong with my first script? Or does ping.exe not have errorlevels at all? UNIX is an operating system, OS/2 is half an operating system, Windows is a shell, and DOS is a boot partition virus.

I've gotten it to work if the host is found (errorlevel 0), but not if the host isn't found (errorlevel 1). Here's the revised script: :start cls @echo off title getMAC echo Clearing ARP Cache . . . netsh interface ip delete arpcache echo Enter IP address of remote computer: set /p ip= for %%i in (%ip%) do (ping -n 1 %%i if %errorlevel% == 1 ( goto fail ) else ( cls arp -a | findstr "%%i" ) ) pause goto start cls :fail echo Host not found, or not alive . . . goto start When the errorlevel == 1, it doesn't ECHO Host not found, or not alive . . . It just goes to :start. Any suggestions? Thanks, Tony login: yes password: dont have one password is incorrect login: yes password: incorrect

Hi Tony, Try this: [I dunno arp, but I think you'll get the idea.] ::== checkIP.bat @echo off :newIP set /p ip= ip num ? if %ip%'==0' goto :eof ping -n 1 %ip% | find "Reply" > nul if errorlevel 1 echo no reply && goto :newIP goto :newIP :: DONE Enetring 0 gives you a way out. ===================================== If at first you don't succeed, you're about average.

Alright, I'll give it a try and post back. Thanks alot, Tony login: yes password: dont have one password is incorrect login: yes password: incorrect
