Hi Hilbert, We will add this as a feature request! Thanks for the feedback.
Does somebody know if it's possible to find the 'failed logons' for a machine through the vWorkspace Powershell cmdlets? As far as I know there is no option for this in the get-qvwcomputer cmdlet and the qvwcomputer object. Thanks,Hilbert
