Several machines does not install application during maintenance windows

We have maintenance windows set for 4 hours every few 5 days for a bunch of virtual machines. Recently found some machines doesnt not install the application during maintenance windows. It has missed for few scheduled start month ago. I notice that for working machine, the appdiscovery.log will run discovery during maintenance window start. For those failed machine, nothing logged on appdiscovery.log during maintenance windows start, and those apps keep showing status as waiting for next available maintenance schedule. I can manually run the application deployment evaluation manually during maintenance windows timing and the app will start install. I am not sure why it happens on some machines. Any idea?

Check the health of the client.

Client looks healthy, for other application that bypass maintenance windows are install directly. This is only happens for application but not package. Only the app is not going to start during maintenance windows. I not sure is there any specified logs can be checked. I checked the servicemanagerwindow log and i can see it activate the maintenance windows during the defined time range.

Have you reviewed the ServiceWindowManager.log on these systems?

Attached with servicewndowmanager.log. I have set a new maintenance windows at 7pm, and there is a dummy application assigned and having the status "Waiting for next available maintenance schedule". On 7pm, the dummy application still not install with same waiting next schedule status.

I can see the servicewindowmanager.log started the active maintenance window and program can run = true, but it still doesn't install the app.

Hi @Viccc-1464,

Please check if the application could be installed in some issued client without maintenance windows, if it could be installed normally, it seems that there are something wrong with maintenance windows.

Besides, we could check Scheduler.log, it records activities of scheduled tasks for all client operations.

yes, the application could installed. On problematic machines, i also deploy a test application that bypass maintenance windows. No issue at all for installation. Definitely something wrong but i can't find where is it.

I have another machine having similar issue, i just reinstall sccm client then it fix the issue. However, this might be too overkill and i still struggling to find the root cause and best way to get it resolved.

I suggest opening a support case here as there is some important piece of info that is not evident causing the behavior you are seeing but without a more in-depth review of the environment, this will be difficult to discover.
