When attempting to create Machine Catalog using Machine Creation Service the task fails with "ErrorID: Image preparation step 'EnableDHCP' failed".
Catalog creation fails when attempting to query and enable DHCP and an exception is given. System.Management.ManagementException: Critical error.

To fix the issue, you need to rebuild the WMI Repository. Run the following script on the master image to test if WMI can be queried. If the script runs successfully WMI repository does not need to be rebuilt.

$mgmtScope = $null
$condition = "PhysicalAdapter=TRUE and AdapterTypeId=0"
$selectedProperties = $null
 
$mgmtScope = New-Object System.Management.ManagementScope
$mgmtScope.Path.NamespacePath = "root\cimv2"
 
$ObjectSearcher = New-Object System.Management.ManagementObjectSearcher($mgmtScope, (New-Object System.Management.SelectQuery("Win32_NetworkAdapter", $condition, $selectedProperties)))
$enumOptions = New-Object System.Management.EnumerationOptions
$enumOptions.EnsureLocatable = $true
$ObjectSearcher.Options = $enumOptions
$adapters = $ObjectSearcher.Get()
 
$adapters
 
foreach($adapter in $adapters)
{
Write-Host $adapter.Name
}
