SYMPTOMS
When logging on to a computer immediately after restarting it, you receive an access violation in Lsass.exe that causes the security subsystem to fail, rendering the computer inoperable until you restart it. The error occurs only if you log on immediately after the CTR+ALT+DEL prompt appears. If you wait a few minutes, the logon attempt will be successful.



CAUSE
A timing issue that prevents Netlogon from reading the cached domain list from the registry causes this error. Netlogon fails to obtain a handle to the registry, and then attempts to use the uninitialized handle to read in a value, causing the access violation.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
