No, the AClient and DAgent only come with Deployment Server 6.n, not Deployment Solution 7.n, which is basically a different product.
But the AClient or DAgent can coexist with the Symantec Management (Altiris) Agent with the Deployment Plug-in.
Deployment Server 6.9 is a great backup for SMP 7.0, if you need to cleanly reinstall Agents etc.
