Event ID 5723: The session setup from computer '…' failed because the security database
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.
The session setup from computer '…' failed because the security database
Event 5723
NETLOGON
System log
Message and fields (as Event Viewer shows them)
The session setup from computer '…' failed because the security database
does not contain a trust account '…' referenced by the specified computer.
USER ACTION
If this is the first occurrence of this event for the specified computer
and account, this may be a transient issue that doesn't require any action
at this time.
If this is a Read-Only Domain Controller and '…' is a legitimate machine
account for the computer '…' then '…' should be marked cacheable for this
location if appropriate or otherwise ensure connectivity to a domain controller
capable of servicing the request (for example a writable domain controller).
Otherwise, the following steps may be taken to resolve this problem:
If '…' is a legitimate machine account for the computer '…', then '…'
should be rejoined to the domain.
If '…' is a legitimate interdomain trust account, then the trust should
be recreated.
Otherwise, assuming that '…' is not a legitimate account, the following
action should be taken on '…':
If '…' is a Domain Controller, then the trust associated with '…' should be deleted.
If '…' is not a Domain Controller, it should be disjoined from the domain.
