SYMPTOMS

Consider the following scenario. You have a computer that is running Windows Server 2008 or Windows Vista. The Stored User Names and Passwords feature is enabled. Additionally, this feature has stored various user names and passwords. In this scenerio, you encounter one or more of the following problems:
  • You cannot log on to the computer when you use a domain user account. The logon process stops responding while it tries to process Group Policy settings. However, you can log on to the computer when you use a local user account.
  • The Network Location Awareness service stops responding. Additionally, you cannot exit this service.
  • Several services stop responding. After a while, the system stops responding.
  • When you try to browse the shared SYSVOL folder on a domain controller, Windows Explorer (Explorer.exe) stops responding.
  • When you disable a network adapter, the disable operation stops responding.
  • When you work in the Network and Sharing Center, the Network and Sharing Center stops responding.
To resolve these problems, you have to restart the computer. These problems frequently occur on servers where many logon operations and many logoff operations occur. For example, this problem frequently occurs on a terminal server.

CAUSE

This problem occurs because of a deadlock in the Lsass.exe process.

When the Lsass.exe process accesses stored user names and passwords, the process has to decrypt the user names and passwords. The process uses the Data Protection API (DPAPI) master key to perform this operation. If the Lsass.exe process cannot decrypt the user names and passwords by using the DPAPI master key, the process requests a backup key from a domain controller. However, if another thread in the Lsass.exe process is contacting the same domain controller to perform another authentication, a deadlock situation occurs.
