I had a scenario, where even if machines had proper maintenance windows and client settings assign to them, yet machines were not rebooting.
Further, on Troubleshooting, I found that there were many collections that had expired windows, so even if the machine had an active maintenance window, you are going to have a tough time on patching day.
Let us jump to the query which lists all collections having Maintenance Window.
select c.Name as 'Collection Names', sw.Name as 'Maintenance Window Name', sw.Duration, CAST(sw.StartTime as date) as 'Start Date', case when sw.RecurrenceType ='1' Then 'None' when sw.RecurrenceType ='2' Then 'DAILY' when sw.RecurrenceType ='3' Then 'Weekly' when sw.RecurrenceType ='4' Then 'MONTHLYBYWEEKDAY' when sw.RecurrenceType ='5' Then 'MONTHLYBYDATE' else 'unknown' end as 'Recurrence Type', c.Comment,sw.Description from v_ServiceWindow sw join v_Collection c on c.CollectionID = sw.CollectionID order by sw.StartTime
Now you can find all collections having an Expired maintenance window. It’s time to remove the expired maintenance window which was only one set up to run once. SQL query also share this information via “Recurrence Type” values
Conclusion: If one machine is part of multiple collections where one collection has an active maintenance window and the other one having an expired maintenance window such workstations are going to have issues.
