Altiris 7.1 - Task does not run until agent is reset

Hi,

I've created an image deployment job which contains a final task that joins the client to the domain.  The job runs successfully i.e. reboots to PXE, erases the HDD, deploys the image and boots back into production but the last join domain task will not run until the agent is reset on the client.

When the agent is reset the client still has the same guid but switches task servers, which seems to kick in the join domain task.

If I dont reset the agent the task is never run.  If I run a manual join domain quick task it works without resetting the agent.

I have tried recapturing my image via altris and recreating my deployment job but this hasn't fixed the problem.

Any help would be greatly appreciated

Thanks
