I have a lot of old machines in a tasks summary page view from Deployment Reports.

These machines are old test or pilot machines that are no longer in the domain.

Can I clean this up? Delete the pc's that are no longer on the domain? This way I get an accurate count of who has a task installed

Thanks for all of your hard work. It allows me to not have to work as hard!

Deleting machines from the Console won't necessarily remove the machine from the deployment report.  The reports will show the results of all the deployments; if a computer has been deleted, its results will still be included.  In version 6, you can add a filter to exclude deleted computers from the deployment reports.

Detecting computers that are no longer active is easy in version 6, simply sort by the "Last poll" column to see which computers haven't polled in a reasonable amount of time.  In version 5, assign a blank Package Task to all the computers in your channel.  Those that remain pending after a period of time should be investigated to see if they can be deleted.

Another option to see who has which Tasks installed would be to create a Configuration Group that is based on a registry key or file that is unique to the piece of software in question.  For example, you could check to see which computers are using the 6.0.1.22 version of the Client by creating a User-defined group based on the following rule:

<File Version> "C:\Program Files\Prism Deploy\Client\PTClient.exe" = "6.0.1.22"
