"7/17/2014 12:45:16 PM","There are no registered Task Services on the SMP. This is expected in case of new SMP installation - the local SMA installed on the same machine as NS needs some time to register on the NS. If this issue persists for long time, check Site Server settings and troubleshoot SMA functionality on the NS (make sure it can send basic inventory and receive policy updates). Make sure at least one Task Server is deployed.","Altiris.TaskManagement.ClientTask.AgentWeb.GetClientTaskServers.FilterServers","w3wp.exe","12","Warnings"

If after fixing the initial issue with the steps provided above and the SMP has the Task Services installed, if the only one remaining is "There are no registered Task Services on the SMP" check under "SMP Console>Settings>Notification Server>Site Server Settings>Site Management>Site Server Settings>Task Service>Settings" that you don't have the SMP targeted on 2 or more Task Server Settings policy. If so, remove and keep it on only one policy.
