MicrosoftHi sutliff1805,
thanks a lot for a detailed description of your issue!
I just checked again all GPOs, but none have the setting you mention configured. I also monitor the registry on a bunch of devices to see when and by which process the "UpdateServiceUrlAlternate" registry entry is being altered, in majority of cases it's being removed by svchost.exe and in a scenario that we don't observe update installation issues, it's being re-created by the same process up to 3 seconds later. So I see this as some conflict, the interesting thing is, this doesn't happen at every policy processing cycle ..., it can be untouched for a few days, then it's removed and re-created.
Another scenario, is that the registry entry is being removed by svchost.exe and gone for up to 1,5h and re-created by "C:\Windows\System32\wbem\WmiPrvSE.exe" - in the time, where the entry is missing, clients cannot download content.
Using Policy Analyzer, I have reviewed the "C:\Windows\System32\GroupPolicy\Machine\Registry.pol" file, while the issue was present and "UpdateServiceUrlAlternate" was missing there ..., so I see it as missing in Local Policy. Forcing a machine policy retrieval cycle on the client, doesn't fix the problem, only a client re-installation restores the setting in "C:\Windows\System32\GroupPolicy\Machine\Registry.pol"
So if "C:\Windows\System32\GroupPolicy\Machine\Registry.pol" is altered by svchost.exe, should I turn my attention to the MECM client/client settings? Is it possible to have a MECM client settings conflict? They have priorities ...
