My issue is about the same as kennedy2008 about "Event ID 5723 need to remove netlogon entries
. I follow all the steps but I couldn't figured out my issue. My problem is
1. Cant' ping the device that shown on the event log.
2. There no DNS record for that device.
3. I do not know the physical location of this computer.
4. Couldn't search that device in Active Directory, even search in the forest domain.
Event ID 5723
The session setup from computer 'COBBGR5J1' failed because the security database does not contain a trust account 'COBBGR5J1$' referenced by the specified computer.
If this is the first occurrence of this event for the specified computer and account, this may be a transient issue that doesn't require any action at this time. Otherwise, the following steps may be taken to resolve this problem:
If 'COBBGR5J1$' is a legitimate machine account for the computer 'CCOBBGR5J1', then 'COBBGR5J1' should be rejoined to the domain.
If 'COBBGR5J1$' is a legitimate interdomain trust account, then the trust should be recreated.
Otherwise, assuming that 'COBBGR5J1$' is not a legitimate account, the following action should be taken on 'COBBGR5J1':
If 'COBBGR5J1' is a Domain Controller, then the trust associated with 'COBBGR5J1$' should be deleted.
If 'COBBGR5J1' is not a Domain Controller, it should be disjoined from the domain.
