Some things to check:
* Verify there is a Create NS Creds comp in your model pointing to the SMP you want to run against before this comp
* Verify the "NS Web Service" solution is installed on your SMP. the GetAll*Components are basically method calls to the ResourceModel web service delivered by this solution. This should be delivered as a prereq to the Workflow solution, but please verify.
* The "AltirisOutput" namespace leads me to believe that you're using the GetAllAssets comp geared to an NS6. Please search for a GetAllAssets comp that has a namespace that starts with "Altiris7.Resource...". This differentiates it for a generated NS6 resource comp, which has a namespace that starts with "Altiris.Resource...". You can check the name space on the settings tab of each component in the Component Class Name.
If there are no GetAllAssets comp for an SMP/NS7, you can try regenerating the resource comps against a SMP that has the Asset solutuion installed. The Get All Uncategorized Assets may be an appropriate comp for you as well.
