Vista - Win32_NetworkingAdapterConfiguration class and SetDNSSuffixSearchO

So I have some Powershell code which I am using to set the variables on the
TCP/IP stack of a Windows 2008 Web server.

So far I have successfully set "IP Address", "Subnet Mask", "Gateway", "DNS
Servers" but cannot set the "DNSSuffixSearchorder". When I try Powershell
tells me the method doesn't exist.

The error I receive is...

Method invocation failed because
[System.Management.ManagementObject#root\cimv2\Win32_NetworkingAdapterConfiguration] doesn't contain a method named 'SetDNSSuffixSearchOrder'.

The code I am using is...

$DNSSuffixes = @("domain.com", "subdomain1.domain.com",
"subdomain2.domain.com")

Get-WmiObject -class win32_networkadapterconfiguration | where-object
-filterscript { $_.IPEnabled -eq ‘True’ } | foreach-object -process {
$_.SetDNSSuffixSearchOrder($DNSSuffixes) }

A check with the windows tool WBEMTEST shows a method called
"SetDNSSuffixSearchOrder" under the "win32_networkadapterconfiguration"
class.

A check of the Microsoft website document
"http://msdn.microsoft.com/en-us/library/aa393296(VS.85).aspx" states "The
SetDNSSuffixSearchOrder WMI class static *****method***** uses an array of
string elements to set the suffix search order. Notice the bit surrounded in
*****'s

A check in powershell using the Get-Member cmdlet shows no
"SetDNSSuffixSearchOrder" method but does show a "DNSDomainSuffixSearchOrder"
property.

So what going wrong here? If anyone can help shed light on this little puppy
next time your in New Zealand I'll buy you a beer or two...honest...I have
been banging my head against the wall for a wee while on this.

Hi Matt,



You need to bind to the win32_networkadapterconfiguration class to get reference
to SetDNSSuffixSearchOrder() as it is a static method (not available on the
class instances):


Get-WmiObject -list win32_networkadapterconfiguration | gm set*

- or the [wmiclass] type accelerator -

[wmiclass] "win32_networkadapterconfiguration" | gm set*



Try:

$nic = [wmiclass] "win32_networkadapterconfiguration"
$nic.SetDNSSuffixSearchOrder(@("suffix1.com","suffix2.com","suffix3.com","suffix4.com"))



BTW, when you compare against boolean values, instead of true/false use $true/$false.
Here are some options for boolean comparisons:


to compare for true:

where { $_.IPEnabled -eq $true}

or simply:

where { $_.IPEnabled }



and for false values (all are the same):

1. where { $_.IPEnabled -eq $false}
2. where { -not$_.IPEnabled }
3. where { !$_.IPEnabled }

Hi Kris,

Can you try this, it is working for me, locally or remotely (xp or vista):

$server = "ServerName"
$nic = [wmiclass]"\\$server\ROOT\cimv2:Win32_NetworkAdapterConfiguration"
$nic.SetDNSSuffixSearchOrder(@("suffix1.com","suffix2.com","suffix3.com","suffix4.com"))

BTW, you can also set it through the registry:

HKLM\System\CurrentControlSet\Services\TCPIP\Parameters\SearchList

Just update/create the above reg value (REG_SZ) with a value like:

"suffix1.com,suffix2.com,suffix3.com"


You can find a set of registry functions on my blog:

Hey, Shay

This is exactly what I typed in all though it was from a windows 2008 server
But setting throught the registry is working.
$server = "ServerName"
$nic = [wmiclass]"\\$server\ROOT\cimv2:Win32_NetworkAdapterConfiguration"
$nic.SetDNSSuffixSearchOrder(@("suffix1.com","suffix2.com","suffix3.com","suffix4.com"))

Thanks
For you help
