title: Active Directory WMI Event Watcher for a modification on a group within in specific OU
body: <p>Powershell question, I want to register a WMI Event watcher to monitor an AD group modification and I am getting a WMI quota violation. Any thoughts on how to do this or optimize the WQL query?</p>
  
  <pre><code>$query = "Select * FROM __InstanceModificationEvent Within 10 Where TargetInstance ISA 'ds_group' AND TargetInstance.DS_distinguishedName like '%VPSA_Exchange_Mailbox_Groups%'"
  </code></pre>
  
  <p>The OU I want to watch is the one that is contained in the DN, but maybe there is a better way? Thanks!</p>
