Domain controller ldap query log. This article describes three unrelated issues that may occur on a windows server 2012 r2 based domain controller. We use the active directory attribute useraccountcontrol for this ldap search. To collect the domain controller names from the active directory forest you can run dsquery server o rdn c temp dclist txt command. Query the primary dns server for the all domain controller srv records in the domain these have the format of ldap tcp mydomain local this will return an entry for each dc in the domain.

Also a complete log of the service is recorded. Incorrect results in ldap query domain controller restarts or user logons are denied in windows server 2012 r2. This powershell script connects to each domain controller specified in the dclist txt file and then collects the name of the event log to query the destination domain controllers from the querylogs txt file. The selfadsi tutorial article about ldap filters shows in detail how to search for single flags in such bit fields for the general explanation of ldap searches read the selfadsi chapter searching ldap objects in the directory.
