Question

Code like this,

try { $NIC = Get-WmiObject Win32_NetworkAdapterConfiguration -ComputerName $Computername -Credential $Credential -filter "IPEnabled = $TRUE" }

catch [GetWMICOMException]
{
    "Error 1"
}
catch [System.UnauthorizedAccessException]
{
    "Error 2"
}

get an error like:

Can’t find type [GetWMICOMException]:

catch [COMException] Same

catch [System.Runtime.InteropServices.COMException] just ignored

How can I catch it?

Get-WmiObject : RPC server was unavailable. (Exception HRESULT: 0x800706BA)
F:\PowerShell Scripts\Project1.NetReconfigurer\proj1.ps1:36 :33
+             $NIC = Get-WmiObject <<<<  Win32_NetworkAdapterConfiguration -ComputerName $Computername -Credential $Credential -filter "IPEnabled = $TRUE"

+ CategoryInfo          : InvalidOperation: (:) [Get-WmiObject], COMException
+ FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand

First. The error is a non-terminating error, so it just notifies. If you want to catch a non-terminating error, use -ErrorAction Stop. Also, I don’t think COMException is an exception you can catch. Try this instead:

try { $NIC = Get-WmiObject Win32_NetworkAdapterConfiguration -ComputerName $Computername -Credential $Credential -filter "IPEnabled = $TRUE -ErrorAction Stop}
catch [System.UnauthorizedAccessException]
{
    "Error 2"
}
catch [Exception]
{
    if ($_.Exception.GetType().Name -eq "COMException") {
        "Error 1"
    }
}
