KarolJ Hello,
- Yes, it was set several years ago in a domain group policy to force all domain joined clients to connect to WSUS where the ConfigMgr client was published as a mandatory update (wsus deployment of ConfigMgr client). We changed this to 'Not Configured'. The 'Set the alternate download server' was blank and I forgot that it's a setting on this template that is enabled so therefore a blank field is still a setting.
- Yes, all clients, but only w11 22h2 and 23h2 clients obtain the monthly cumulative updates via UUP and thus only they were having problems. After setting to 'not configured' I could GPUpdate a pc, restart it, and almost immediately it would begin downloading the updates from the on-site DP.
- The "UpdateServiceUrlAlternate" is the registry value that is set by the GPO.. \HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate
I persistently monitored this value as ConfigMgr is supposed to set it and I kept wondering why it was not set -- although ocassionally I would find it set. Many computers were managing to patch after several days so my theory is that ConfigMgr would set it and begin working then break when GPO reset it to a blank every 15 minutes..
- Regarding Client Settings
-- Client Cache Settings: "BranchCache" is NO, "peer cache" is NO
-- Delivery Optimization:
"Use Microsoft Connected Cache server": NO.
"Use CM Boundary Groups for DO Group ID": this can be YES (and on each Boundary Group it's set to not allow peer downloads (e.g. "Allow peer downloads in this boundary group" is not enabled). thus forcing everyone to use their local DP - and it is YES in my lab but in production it is set to NO.
-- Software Updates: "Allow clients to download delta content when the option is available": No.
In my 8-month long case with Microsoft I learned that with w11 UUP, after I think the Sep or Oct cumulative update and on ConfigMgr build 2309 the updates should start working.
WUA (Windows Update Agent) invokes Windows DO (Delivery Optimization) to locate the content and DO uses delta download. Delta download then creates jobs, seen in CMBitsjob.log. Delta Download then creates the Content Transfer Manager request. CTM then requests the location (DP or branchcache or peercache) and creates the Data Transfer Service (DTS) job. DTS then downloads the content.
