Hi friends,

This is log it saying:

I agree 100% with @Wolfgang . I had customer with exact same issue and it was solved by patching their AD server.

Maybe there are new updates or configuration on your domain controllers.

Have a look Check Point response to CVE-2021-26414 - "Windows DCOM Server Security Feature Bypass"  and AD-query failed with Microsoft Windows Server 2022 

Check your domain controller logs and better solution will be the identity collector not AD query.

I check with AD sysadmin, he just upgrade this security patch KB5014702. Not sure if this causes AD query failure ?

I am experiencing the same issue right now after AD received the june patch KB5014702.

However my AD colleagues told me that this is the most recent update. Therefore I'm not quite sure what you mean by "Patch AD server with latest updates."
