I have 3 Exchange 2003 2 node clusters running on Server 2003. When looking at the active node (or from the virtual server itself), no updates at all show up in the Software Updates tab of the Altiris Agent. The passive node has everything listed like normal, including an Update Scheduled entry for MS09-003, as expected. I've run a compliance and vulnerability report, and all nodes of all clusters show vulnerable, and all 3 passive nodes have the update scheduled. Any help would be greatly appreciated.
