Windows Server 2022 not download WSUS updates

[Theldron]

Hi all,

 

Hope you are well.

 

I am setting up 2 new DCs on Server 2022 as our current ones are on Server 2016 and LAPS doesn't work with Win 11 24H2 you need to use Server 2019 or above.... but that's another story.

 

I have server 2022 installed and on the domain but when I try to get it to download updates, it is either stuck on 0% or 10%. I have ensure that WSUS has the correct server updates - 21H2 I believe for 2022. But it is just stuck. On 2019, I had to change the download mode for Delivery optimisation to bypass for that to work with WSUS. But that setting has been depreciated.

 

Any other ideas?

Maybe look to move to something like Action1 for managing server updates.

Thanks but would prefer to stick with Microsoft WSUS or is WUFB ok?

WUfB is certainly better IME - I stuck with WSUS for a long time but it was labour intensive, unreliable and a massive storage black-hole. I don't miss it, and it was issues like this that finished it (then the database died for a second time).

I've got Server 2022 downloading from WSUS server just fine here.

 

Have you got the ESD filetype fix in place? There was at least one fix like this that needed doing so that certain large files would flow through WSUS correctly - https://community.spiceworks.com/t/fix-wsus-clients-stuck-on-0-download/1012611

 

Do you have any WUfB settings in your policies? If so, remove these immediately as they will try and bypass WSUS as a source.

Hi thanks for that.

 

I have looked at the link you put in but I already have a .esd in place. Do I get rid of this?

 

 

No I don't have anything in place for WufB yet. I use Server 2016/2019 and they download updates fine, it just seems to be 2022.

Looking on my config, I replaced that line on mine. You may want to save that string somewhere just in case you need to put it back, though!

@DavR Thanks mate, but still stuck at 0%. This is driving me potty. 2019 is fine.
