Lsass.exe crashes soon after you use a smart card to log on to a computer that is running Windows XP SP2, Windows Server 2003 SP1 or Windows Server 2003 SP2Article ID: 895325 - View products that this article applies to.

No association with any real company, organization, product, domain name, e-mail address, logo, person, places, or events is intended or should be inferred. On This PageSYMPTOMSWhen you use smart card authentication to log on to a computer that is running Microsoft Windows XP Service Pack 2 (SP2), Windows Server 2003 Service Pack 1 (SP1) or Windows Server 2003 Service Pack 2 (SP2), the logon process is successful. However, after several moments, the Lsass.exe process encounters an access violation and terminates. You do not experience this problem on a computer that is running Windows XP Service Pack 1 (SP1) or the release version of Windows Server 2003. CAUSEThis problem occurs because of heap corruption that may occur in the Lsass.exe process when you log on by using a smart card. This problem occurs if the subject field of the certificate on the smart card is in a particular order. In this scenario, if the domain component of the subject field is not in the last few attributes, Lsass.exe experiences heap corruption. Then, the process crashes. The following example subject fields illustrate this problem. Example 1: DC = WIDGETS In this example, the domain component part of the subject field is not in the last several attributes of the subject field. In this example, Lsass.exe experiences heap corruption.DC = MSN CN = dalexander CN = Users Example 2: CN = David Alexander
In this example, the domain component part of the subject field is in the last several attributes of the subject field. In this example, Lsass.exe does not experience heap corruption.CN = Users DC = corp DC = tailspin DC = toys DC = com RESOLUTIONHotfix information for Windows XPA supported hotfix is available from Microsoft.
