Windows 7 account lock outs Event ID: 4776 Authentic Package: MICROSOFT_AUTHENTICATION_pACKAGE_V 1_0
Hello, hope someone can help, users are getting intermittently locked out by domain controllers which are Windows 2008 R2
hosted in VMWare VSphere 5.0.
They are logging on with local accounts to Windows 7 Enterprise desktops which are
not part of the domain. They connect to network shares,sharepoint,Instant Messenger by
provider their domain log on credentials.
Intermittently a DC will log a bad password and lock them out, preventing them from accessing
network resources, however their password has not changed.
The error log on the server shows the following:
Log Name: Security
Source: MS Windows Security
Event ID: 4776
Task Category: Credential Validation
Keywords: Audit Failure
Authentic Package: MICROSOFT_AUTHENTICATION_pACKAGE_V1_0
Logon Account: user's network log on account
Source Workstation: Users Windows 7 Desktop
Error Code: 0xc000006a
I have launched "control userpasswords2" from the run command and cleared any cached account passwords on the desktop machine but this did not fix the issue.

Hi,
This type issue occurs should be more related to domain controller settings.
I find a similar case from the third party website. For your reference:
