The customer has the following scenario:
Since he can't uninstall the Altiris Agent using the agent uninstall task because DeepFreeze is installed (also it can apply to machines that were left behind in another domain or after the company split-off but the Altiris Agent is still active on those machines), the customer don't want those machines showing in the SMP Console. He doesn't want to track them anymore because those are no longer their computers.
ITMS 8.5, 8.6
There are few options:
1. If you don't want to manage them, you can just delete them directly from the SMP Console under Manage>Computers>select computer>right-click>Delete
or you can just "retire" them: Manage>Computers>select computer>right-click>CMDB Functions>Set Asset Status>Retired
These options should remove these machines from been considered active and visible on your Manage>Computers page.
2. Now, if those machines can still access the SMP server because those machines have the CEM (cloud-enabled management) mode turned on, there is the chance that they can come back and be added back again when they send basic inventory. You can "revoke" access to those machines:
a) Go to SMP Console>Reports>Notification Server Management>Registration>Agent Registration Status
b) Change the "period" on the report to 1 or 2 days for example, set "status" to "All", run the report and see if those machines came back. If so, right-click on the machine on the Report and select "Revoke Internal agent trust". See more details under "Viewing and Managing the Agent Registration Status"
When you "revoke" access to these machines, they can't get new configuration or send info back because the access has been revoked or denied. The Altiris Agent itself on those computers will fail to reach out to the SMP server.
c) Then, you can delete or retire the machine(s) from your SMP Console as mentioned in step 1 above.
