This article will walk you through changing the DNS server using NetSH on remote computers with the remote scripting features in Bozteck VENM Remote Desktop Manager.

Bozteck VENM (VNCScan Enterprise Network Manager) lets you extend its numerous built in remote management capabilities by creating your own scripts that you can push and execute on the computers across your LAN and VPN connections.

Step 1 – Open the Script Editor

With VENM open to the main window shown below, we will create the scrip by clicking on the link in the right side bar titled “Edit Remote Scripts”.  You will find it in the “Deployment Tasks” section.

Step 3 – Author the script

From the scripting engine drop-down, choose Windows CMD.  The default is PowerShell but since we are using a windows command script to perform this action, we will need to choose the correct command processor.

You can paste in a script or author it right there in the editor.  In this case, you can paste the script below:

SETLOCAL EnableDelayedExpansion

SET adapterName=

FOR /F “tokens=* delims=:” %%a IN (‘IPCONFIG ^| FIND /I “ETHERNET ADAPTER”‘) DO (
SET adapterName=%%a

REM Removes “Ethernet adapter” from the front of the adapter name
SET adapterName=!adapterName:~17!

REM Removes the colon from the end of the adapter name
SET adapterName=!adapterName:~0,-1!

netsh interface ipv4 set dns name=”!adapterName!” static primary
netsh interface ipv4 add dns name=”!adapterName!” index=2

ipconfig /flushdns


The window should look like the one shown below.

Step 4 – Deploy the script to a remote computer

After you have saved your new script, head back to the main Bozteck VENM window and select one or more computers.  With those selected, chose your new script from the dropdown in the right tool area shown in the screen shot below.  With those two things selected, press the “Execute” button and watch VENM work it’s magic.
