Windows Defender (Managed) signature updates

[spgsitsupport]

All Policies are in place (I can confirm that correct entries are in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Microsoft Antimalware\Signature Updates )

 

Update works manually (by clicking Update Definitions), but it does not seem to auto update

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Microsoft Antimalware\Signature Updates]
"AuGracePeriod"=dword:00000b40
"SignatureUpdateInterval"=dword:00000004
"ScheduleTime"=dword:00000078
"ScheduleDay"=dword:00000008
"SignatureUpdateCatchupInterval"=dword:00000001
"FallbackOrder"="FileShares|InternalDefinitionUpdateServer|MicrosoftUpdateServer|MMPC"
"DefinitionUpdateFileSharesSources"="\\\\someserver\\SCEPDefinitions"

I really lose my faith in SCEP client

FileShares was in the end the only source that works at all

 

Anybody has any pointers (and I do not mean recommendation of replacement with ie Kaspersky)
