SYMPTOMS

On a Windows Server 2008-based computer or a Windows Vista Service Pack 1-based computer, all services or processes that require authentication may stop responding.

For example, when you type your user name and password, the system stops responding at the "Welcome" screen.

CAUSE

The problem occurs because of a race condition that leads to a deadlock condition in the Lsass.exe process. When the deadlock condition occurs, the Lsass.exe process cannot handle authentication requests. The problem is most frequently triggered when the system is under a heavy load and the computer password is changed.

RESOLUTION
