Hello,
I noticed while trying to enable LEDBAT on a Distribution Point collocated on a site server that it keep disabling itself every hour.
When enabling it: distmgr.log shows LEDBAT beeing enabled
Running Get-NetTCPSetting and get-NetTransportFilter shows that LEDBAT have been succesfully configured as congestion provider for the InternetCustom template, this template is used in 2 transport filter (TCP 443 + TCP 80)
One hour later, the congestion provider for the InternetCustom template is restored to it's default value (CTCP on windows server 2016) and the 2 transport filters have disappear.
Digging a bit, I ended up finding in the Windows Powershell log that every hour, the 2 following commands are running:
- powershell.exe -Command Remove-NetTransportFilter -SettingName InternetCustom -Confirm:$false
- powershell.exe -Command Set-NetTCPSetting -SettingName InternetCustom -CongestionProvider Default
Using procmon, these powershell commands are created by the smsexec process. immediately before and after these powershell command something is written in WCM.log, which contains
Details about the SCCM infrastructure:
- OS Server 2016: CAS + SUP
- OS Server 2016 : Primary site + SUP + DP
- OS Server 2012R2 : DP
SCCM version : 2103 + HFRU KB10036164
Subsequent HFRU does not seems to fix what I'm facing.
Any thoughts?
