Yesterday I installed a 2208 cumulative update (KB5016690) on one DC, after the reboot, there were some warnings in the event viewer: 6038 - LsaSrv, 2886 – ActiveDirectory_DomainService, and 3041 LDAP Interface, today just the event ID 3041 showed.
I looked it up on internet, and for the event ID 2886, there is a policy setting that people recommend: “Computer Configuration>Policies>Windows Settings>Security Settings>Local Policies>Security Options.
Right-click on Domain Controller: LDAP Server Signing Requirements and select properties.
Check off Define this Policy Setting.
Select Require Signing in the drop-down box"
I am not totally sure if this going to help because this were mainly applied on Windows Server 2008 operating system, there is nothing about Windows Server 2019. I am also not sure why the event ID 3041 is still showing. Is there any other recommendation?
