Updates not installed during windows maintenance

Sergi Díaz Ruiz 125

Afternoon!!

We have correct windows maintenance 68% devices are compliance so we have more than half of devices up to date with this maintenance window. So deploy, boundaries and windows maintenance it's correct.

I need to know two questions...:

1- We have SUG with différents KB's for monthly rollup for example. When you deploy the SUG and have windows maintenance configured, I assume that the updates doesn't install UNTIL all needed updates are not downloaded or already to install. Right? Because as I can see, my clients download 2 of 3 updates and two days later devices download it correctly and automatically.

2- How can I determine if my DP's or Primary site have connection errors in a specific date?

I saw the following on logs:

I have more clues in another logs but here is very very obviously that the client doesn't know have pending downloads. We have window maintenance for 15/09 from 08:00AM to 12:00PM (4 hours)

So...... Content has downloaded after the windows maintenance.
Is this the root cause why KB's are not installed?

Why client doesn't know? Because I upload it Friday 13/09 and this device for example download it Sunday at 15:32 PM

What's up these days? Why doesn't download the update in 2 days?

TIA !!!

Hi, @Sergi Díaz Ruiz

Thank you for posting in Microsoft Q&A forum.

You have window maintenance for 15/09 (Sunday) from 08:00AM to 12:00PM (4 hours), but the device download it Sunday at 15:32 PM, does the device has the same time zone as the maintenance window? By default, the maintenance window do not use the UTC time zone.

@AllenLiu-MSFT thanks for answer,

This windows maintenance have a lot years working fine ... It's not problem like this... It's just this weekend and 106 devices, the rest up to date correctly during maintenance window.

I need to troubleshoot, but I don't know where start xD

I don't know how updates works in maintenance... First download all and later install?

Why not downloaded during windows maintenance? and downloaded at Monday...

TIA!

Hi, @Sergi Díaz Ruiz

You may start from checking ServiceWindowManager.log on clients, it records details about the evaluation of maintenance windows.

Hi! Yes, I can add the log but I think is not the problem, the problem is that server can't reach the distribution point to download the content. It's very clear... But I don't know why they can't reach the distribution point, this is what I should find...

Why the devices can't reach the distribution point during weekend only... Because Monday download the content correctly...

Can someone help me with this?

TIA!!

Morning,

I check it but for example, the updates was installed at weekend,... For example the updatedeployment.log is overwrite ..... I have no info about it ...

At other hand what I can see is this:

Not reporting any download events to server. No recent downloads found .

In contenttrasfer.log

After one weekend, at monday, the update download correctly as you can see in the screenshot.

I don't know why, because I can see how the list of DP is empty:

After few days as you can see... Parse download completion...

0 distribution points discovered:

With click buton - open in new tab you can see the image with good resolution.
