GroupPolicy Event 1006 ErrorCode 49

    Question

  • Once a day or so I get the event id 1006 with error code 49 from the GroupPolicy client (Windows 8.1 and Server 2012 R2).

    Event ID 1006 means "The processing of Group Policy failed. Windows could not authenticate to the Active Directory service on a domain controller. (LDAP Bind function call failed). Look in the details tab for error code and description."

    And ErroCode 49 is "Invalid Credentials".

    The account listed is sometimes the computers SYSTEM account and sometimes my useraccount. The same second or about a second after Event ID 1006 another Event is logged, ID 1500 or 1501 which means succesful processing of the Group Policy, again using the same useraccount.

    Why does the client think my credentials are bad from time to time? Should I worry or is this just a "feature" to ignore?

    This error code might indicate that the user's password expired while the user is still logged on the computer.

    To correct invalid credentials: 

    1. Change the user's password.
    2. Lock/unlock the workstation.
    3. Check if there are any system services running as the user account.
    4. Verify the password in service configuration is correct for the user account
