Hello,
I need to use wmic.exe to set DNS Suffix Search Order on a computer that has a WMI problem using the syntax below:
wmic nicconfig call SetDNSSuffixSearchOrder (‘abc.com’,‘def.com’,‘ghi.com’)
When I ran the above command inside a CMD command prompt window, it worked fine. The output from a successful launch is shown below.
Executing (Win32_NetworkAdapterConfiguration)->SetDNSSuffixSearchOrder()
Method execution successful.
Out Parameters:
instance of __PARAMETERS
{
ReturnValue = 0;
};
However, when I launched the same command inside a PowerShell console or script, I kept getting the following error:
Invalid format.
Hint: = [, ].
I tried to reformat the data type of the DNS Suffix Search string to different data type, but I kept getting the same error.
I know that I can escape the wmic comma parameter with a pair of quotes like ‘,’, but I still cannot figure out how to format the data within the PowerShell console in order for the wmic command to work properly.
Below is the PowerShell code.
$DNSSuffixes = ‘abc.com’,‘def.com’,‘ghi.com’ # (This will give the object array data type)
or
$DNSSuffixes = [string]($DNSSuffixes | % {$.Split(‘,’)} | % {$.Trim()}) # (This will give the string array data type)
wmic nicconfig call SetDNSSuffixSearchOrder ($DNSSuffixes)
Thanks.
