Request the Partner Management Console be enhanced.
If any client computers have virus definitions that are significantly out of date - say more than 14 days - this information must get propagated up to the Partner Managment Console as an alert condition.
The PMC should obtain this information from the same location as the Computer Summary report. The "Health" column shows computers whose condition is either "At Risk" or "Needs Attention." Sites should be flagged to let partners know they need to either take action or contact the client.
