Changing TCP to dynamic using PowerShell

PowerShell Help
1

That’s my code and I’m having difficulties making it work. It does not change my adapter settings.

#DHCP Function To Enable DCHP On The Local Computer
###############################################################

Function DHCP

{
$Adapt = Get-WMIObject Win32_NetworkAdapterConfiguration | Where {$.IPenable -eq “True”} |`
Foreach-Object {$.EnableDHCP();$_.SetDNSServersearchobject()}
Write-Host “Rebooting Now”
Start-Sleep -s 5
Restart-Computer
}

Part of a bigger code–

Function Main
{
$Host.UI.RawUI.Backgroundcolor = “Black”
$Host.UI.RawUI.ForegroundColor = “Green”
}

Possibly because you have a spelling error its $.IPenabled not $.IPenable

4

Tried that and this error message comes.

5

Looking back I also found one more error -

$_.SetDNSServersearchobject()} suppose to be SetDNSServerSearchOrder()

But still not working

6

looks like another typo its ‘SetDNSServerSearchOrder’ not ‘SetDNSServerSearchObject’

7

oh soz misread your message - ignore that

Function Set-DHCP
{
$Adapt = Get-WMIObject Win32_NetworkAdapterConfiguration -filter “IPenabled = ‘True’” ;
$Adapt.EnableDHCP();
$Adapt.SetDNSServerSearchOrder();
Write-Host “Rebooting Now in 10 Seconds”
Start-Sleep -s 10
Restart-Computer
}

Used that code and managed to make it work :slight_smile:

Just one more thing.

how do I create a desktop shortcut to your script and place it in the c:\users\public\desktop folder, so that all logged in users can have access to it.

You could save it as a module which is a psm1 file. Check your module locations: $env:PSModulePath -split “;”

I tend to put it in C:\Program Files\WindowsPowerShell\Modules*Your Function Name*

then you can just load the module when you open powershell by doing ‘import-module DHCP’ in your case.

11

In fact you wouldn’t even have to load the module you would just type DHCP into Powershell. Really it should be verb-noun so Set-DHCP something like that and then it will run.

when i save it as psm1 file all i get is a blank notepad

Also, I need to make a shortcut on desktop that will execute when double clicked
