  • authentication problem

    Hi,

    i'm experiencing a strange problem, i have 3 dc windows 2000 but i have upgraded the schema to ad2k3, normal authentication is in mixed mode 90% using smartcard with user certificate issued by CA2000 installed in a DC, 5% login/password with time expiration, and 5% with smartcard with user certificate issued by new CA2003.

    The problem is that sometimes the authentiction with smartcard with certificate issued by ca2003 doesn't work with this error:

    Event Type: Failure Audit
    Event Source: Security
    Event Category: Account Logon
    Event ID: 675
    Date: 9/01/2005
    Time: 9:24:28 AM
    User: NT AUTHORITY\SYSTEM
    Computer: DC3
    Description:
    Pre-authentication failed:

    Service Name: krbtgt/company.com

    Failure Code: 0x3E
    Client Address: 172.16.1.126

    thanks

    and kind regards

    Pre-authentication errors are not always an error. Do users actually experience problems?
