Hi everybody,
This is a bit of an odd one. I am getting the SAM database lockout message regularly in the System event log, but it says 'unable to lockout the account of invalid'...
According to the event log, one request is coming from a workstation, the other is coming from the server itself, and both are using the name of the server admin account before I renamed it. See events below. I have run Wireshark on the workstation and could not see any sign of a login attempt. I have looked in the credential store on W/S and Server and can see no mention of this account, ditto Services Logon As.
If anyone is able to make some suggestions as to what to look for next, I would be most grateful.
