Delete ManagementObject but exception occur

[wasishincar]

Hi All,

I am working on deleting disconnected devices in Device Manager.
I write codes as below but get exception that tells something like
"Provider Cannot do attempted operation"
ErrorCode is System.Management.ManagementStatus.ProviderNotCapa ble
How can I delete these connections? Thanks for any reply.

// delete all desconnected device informations first
string strQry = "Select * from Win32_NetworkAdapterConfiguration where
Description='Windows Mobile-based Device'";
ManagementObjectSearcher objDelete = new
ManagementObjectSearcher(strQry);
foreach (ManagementObject objQry in objDelete.Get())
{
objQry.Delete();
}
