Event ID 1025: The DNS server IP … of the response for query … is not configured on the client, client PID …, send blob …, context
Windows Event ID Lookup: What Windows event IDs mean: 4625, 4624, 4740, 6008, 41, 7045, 1102 and 3,000 more, with Windows' own message text, the fields and what to check.
Look up a Windows event ID from Event Viewer, a SIEM alert or a log export: what it means, the fields it records, and what to
check. Many IDs are used by more than one source (event 41 is both a Kernel-Power crash and a boot error), so every definition
is shown, the one people usually mean first. The message text is Windows' own, read from the event providers of
Windows 10.0.26200.0, 2026-10-28; the notes are ours, based on Microsoft's
security auditing reference.

Warning
Message and fields (as Event Viewer shows them)
One or more named pipes or shares have been marked for access by anonymous users. This increases the security risk of the computer by allowing unauthenticated users to connect to this server.
Registry Key: HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters
Registry Values: NullSessionPipes, NullSessionShares
Default Value: Empty (or not present)
Current Value: Non-empty
Guidance:
You should expect this event when modifying the default values of NullSessionShares and NullSessionPipes. On a typical file server, these settings do not exist or do not contain values, which is the most secure configuration. By default, domain controllers populate the NullSessionShares entry with netlogon, samr, and lsarpc to allow legacy access methods.
