I would double check the Update Client task scheduled for this machine. Make sure it is scheduled, enabled, and set to update dats.
You mean the Automated Server tasks on the epo server?
What is the default Update Client task called? I have been here before and tried to create a new task, but the only update option I get is to update sensor deployment client tasks.
You can create a Agent update task on the client tasks tab of the epo system tree page. Click 'New Task' and under type drop down select 'Update (McAfee Agent)'. Click next and make sure that DAT and Engine are selected under package types. Click next specify the schedule and complete the wizard.
Once done send an agent wakeup call to have the clients recieve the task details immediately or wait for the clients to call back as part of their ASCI.
