hi

got a wee powershell script that enable IP to DHCP and its working when i copy the script to powershell with adminsitrator

i would like to make a script instead but it wouldnt let me run it.

$networkConfig = Get-WmiObject Win32_NetworkAdapterConfiguration -filter "ipenabled = 'true'"
$networkConfig.EnableDHCP()
$networkConfig.SetDNSServerSearchOrder()

ipconfig /registerdns

"*****************************************" | Out-File C:\Windows\COMPANY-staticIP.txt -Append
get-date | Out-File C:\Windows\COMPANY-staticIP.txt -Append
ipconfig /all | Out-File C:\Windows\COMPANY-staticIP.txt -Append

how to run the .ps1 with administrator? there is no option to right click -select run as adminstrator

thanks

There is no option to run as administrator on PS1 which is rather strange

Will try that when I'm.back work later

Thanks again

oops you are right.

got the administator option working now but the script is not doing anything, it doesnt set the IP to dhcp. which it does works when i copy/paste the script to powershell (run > cmd right click run as adminstrator)

Not a powershell expert by any means but ive written a few scripts and normally get around this by setting the execution policy in the script.

thanks

how?

Code:

PS C:\Users\infowp\Desktop> C:\Users\infowp\Desktop\dhcp3.ps1

Execution Policy Change

yep working, it moved IP from static to DHCP.

do i have to run set-execution unrestricted first on every PC ?

wesley · 14 Feb 2020 at 16:09

thats more work than change the IP to DHCP via the control panel.

shame there is no real quick way for this.

but thanks guys

There is a quick way are you deploying it to a domain?

could do but the manager said we must ensure every PC must be on DHCP so will the deployment work? we'll never know

wesley · 14 Feb 2020 at 16:19

yes i have access to the DC,

going home now, will run the bypass bit on monday morning

thanks again

wesley · 14 Feb 2020 at 19:01

hi vince thanks again

i dont have the access to DC from home, will have to wait till monday

im confused by what you said "But you can remove the fixed address from the scope of dhcp"

every PCs are issued a static IP address by manual input rather than they have been issued a static IP by deployment.

edit: approx 2300 PC's at 5 centres to be move to DHCP. im responsible for 1 centre with approx 470 PC's

thanks for the post

the network manager designed the network and configured the vlans for each floors and 3 domains, wifi too. (wifi devices are on DHCP). all PC's are issued with static IP corresponding to the hostname and floor.

no problem with networking at all. recently the manager have asked us to move all PC's from static to DHCP....DHCP leasing are already setup ready for the PCs to be taken off the static IP

i just need a very simple way to get the PC's on DHCP. if it was that simple, he would do it via the group policy.

edit: its not my role to dealing with the networking. i'm just an IT techie that responsible for a site with 470 PC's. i have access to the DC. and group policies too.
