Gents,
Recently I found in the Windowsupdate.log on all Windows 2012 R2 servers the following issue.
Windows Update Client tried to download something from https://sls.update.microsoft.com.
I've not configured that. I configured all servers obtain updates from local WSUS. All WU settings are deployed via GPO.
Can anyone shed a light, _why_ is WU client on Win 2012 R2 downloading something from this url ?
How to turn off that ? All server must obtain all updates from local WSUS. Only WSUS server can obtain updates from Microsoft.
I don't see this issue on Win 2008 R2 servers.
Some details from WindowsUpdate.log:
