Windows 7: Windows 7 creating blank txt file after running a batch script

Windows 7 creating blank txt file after running a batch script

I have the following batch script

@echo off

    setlocal enableextensions

    set "baseName=dnshistory"

    set "count=0"
    for /f "delims=%baseName%." %%a in (
        'dir /b /o-d "%baseName%*.txt" 2^>nul'
    ) do ( set /a "count=%%a+1" & goto saveData )

    ipconfig /displaydns | find "Record Name" > "%baseName%%count%.txt"
The problem is that when i run it on my windows 7 desktop, it creates an empty txt file in comparison to my windows 8 laptop, where it creates the dns record that i need.

Does anyone knows why this happens on windows 7 ?

Usually inserting a bunch of "echo" statements will give a hint what's wrong. Just like using MsgBox in other programming languages.

Are you running it from a Elevated Command Prompt? I think that's required.

Run ipconfig /displaydns | find "Record Name" and see if it works. Then try it from a Elevated Command Prompt.
