Script to change PC Name by querying list

Hi All,

Need to some help to create a script that can change the pc name automatically. I can currently do this with no problem but only if I put the new pc name in the script. I want to be able to have one main text (or access database) where all the pc names are listed for each site (grouped by default gateway), then when the script runs it looks at the pc's current default gateway then queries the master file (txt or db) and then picks the next pc name in the list according to the default gateway.

I know thats a lot there, and hope I explained it fine.

Please help.
Thanks

Give this a try.

Change these variables to something accessible on the workstation. Could be server share.
Set NewCompList=C:\AT\NewComputerNames.txt
Set UsedCompList=C:\AT\UsedComputerNames.txt
Set ErrorLogging=C:\AT\Errors.txt

@ECHO OFF
Set NewCompList=C:\AT\NewComputerNames.txt
Set UsedCompList=C:\AT\UsedComputerNames.txt
Set ErrorLogging=C:\AT\Errors.txt
 
if exist "%UsedCompList%" (
    FIND /i "%ComputerName%" "%UsedCompList%" 1>NUL
    if not errorlevel 1 (
        echo %ComputerName% already exist in %UsedCompList% computer name has already been changed once before.
        echo %ComputerName% already exist in %UsedCompList% computer name has already been changed once before.>>"%ErrorLogging%"
        goto :EOF
    )
)
 
Set NewName=
Set MAC=
Set Gateway=
 
for /f "Tokens=11 delims=: " %%a in ('ipconfig /all ^| find /i "Physical Address"') do Set MAC=%%a
for /f "Tokens=12 delims=: " %%a in ('ipconfig /all ^| find /i "Default Gateway"') do Set Gateway=%%a
for /f "tokens=3 delims=]," %%a in ('type "%NewCompList%" ^| find "%Gateway%" ^| find /v /n "" ^| findstr /b /c:"[1]"') do Set NewName=%%a
 
if defined NewName (
    (type "%NewCompList%" | find /v "%NewName%")>"%NewCompList%.temp"
    move "%NewCompList%.temp" "%NewCompList%"
 
    if not exist echo Date,Time,Old Computer Name,Gateway,New Computer Name,MAC Address>>"%UsedCompList%"
    echo %date%,%time%,%ComputerName%,%Gateway%,%NewName%,%MAC%
    echo %date%,%time%,%ComputerName%,%Gateway%,%NewName%,%MAC%>>"%UsedCompList%"
 
    REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\ComputerName\ComputerName" /v "ComputerName" /t REG_SZ /f /d "%NewName%"
    REG ADD "HKLM\SYSTEM\CurrentControlSet\Services\TCPIP\Parameters" /v "NV Hostname" /t REG_SZ /f /d "%NewName%"
    echo Computer name has been changed please reboot!!!
) else (
    echo A new computer name for %Gateway% is not found in %NewCompList%
    echo A new computer name for %Gateway% is not found in %NewCompList%>>"%ErrorLogging%"
)

Open in new window

NewComputerNames.txt

Hi AmazingTech,

The script works nearly perfectly, Just one problem:
when I run it it just waits for a date to be entered manually (found this out when, I run it, it just stops at a point, then if I go to the UsedComputerNames.txt file I see the below:

The system cannot accept the date entered.
Enter the new date: (yy-mm-dd)

after i type in the date, it works perfectly, why would it do this?

Thanks again for the help, after this problem, this script will be perfect.
