There should be two types of pregenerated NS components: one for NS6 and one for NS7+. NS6 components are only exposed in the tree if you have a NS6 registered. Unsure of how they looked when they released, but the NS6 components should be nested under Symantec\SMP in the component tree, and the NS7 components should be nested under Symantec\SMP 7 and have updated icons. Also, the NS7 components should have a "7" somewhere embedded in their namespace (like "Symantec.Generated7.*" or something similar)
The GetAllLocations component is a resource component, and for NS7 that means hitting the webservices in the NS Web Services solution. The actual web service it tries to invoke is the ResourceModel.asmx. A similar web service lived in a different place in the NS6 architecture.
I would verify that you have an instance of the NS Web Service solution on your NS7 that lives at Altiris\NSWebService in IIS, with that ResourceModel.asmx present.
