Altiris runs commands using the context the agent runs under, the local System account. this doesn;t usually have any rights to access external shares like \\servername\deploy.
I'm not sure where the ADSK comes into this?
If you're using Ghost Solution Suite or the old Deployment Server 6.9 you should create a "Distribut Software" Task in your Job.
If you're using Client Management Suite you should ideally use Patch Management Solution but otherwise at least use Software Delivery Solution to create a Software Release with a command line and detection rule and deploy that via Policy.
