Cannot find an overload for "SetDNSServerSearchOrder" and the argument count: "2".

Question

Hello everyone,

I want to change DNS IP via powershell script. The script:

Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE | Where-Object {!$.DHCPEnabled} | ForEach-Object { $.SetDNSServerSearchOrder('8.8.8.8','8.8.8.4') }

After run the script it says:

Cannot find an overload for "SetDNSServerSearchOrder" and the argument count: "2".

I removed 8.8.4.4 script works. How can I solve this problem?

Answer 1

Hi @Emil Mammadli ,

not quite sure if this is the cause, but can you please try this:

$DNSSearchOrder = "8.8.8.8","8.8.8.4"  
Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Filter IPEnabled=TRUE | Where-Object {!$_.DHCPEnabled} | ForEach-Object { $_.SetDNSServerSearchOrder($DNSSearchOrder) }  

Does it work?

Answer 2

When dealing with system-type methods a comma is used to separate parameters. This is unlike PowerShell where commas are usually used to create lists (arrays) and spaces are used to separate unnamed parameters.

The answer provided by @SChalakov creates a list and then passes that list as a single parameter. His answer does, however, contain an omission: it's missing the underbar ("_") character in two places.

$.DHCPEnabled  should be $_.DHCPEnabled  
  
and  

$.SetDNSServerSearchOrder  should be $_.SetDNSServerSearchOrder

Hi @Emil Mammadli ,

please try this one:

 $DNSSearchOrder = "8.8.8.8","8.8.8.4"  
 Get-WmiObject -Class Win32_NetworkAdapterConfiguration -Namespace "root\CIMV2" | Where-Object {$_.IPEnabled -eq "True"} | ForEach-Object { $_.SetDNSServerSearchOrder($DNSSearchOrder) }
