Resolution

Things to check:

1. Please check the registry on the problematic computer and specifically verify that "MachineGuid" in "HKLM\SOFTWARE\Altiris\eXpress\NS Client\NSs" exists and it is not empty.
2. Also check that you did not by mistake manually target the Altiris Agent installation over and over for this machine.
3. And last, reinstall the Altiris Agent and its plug-ins if the above did not help.
