Consider the following scenario:

• A domain member computer is running Windows Vista, Windows Server 2003, or Windows XP.
• On the domain member computer, an application calls the LsaLookupSids function to translate a security identifier (SID) to a user name.
• The user name has been changed on a domain controller.

In this scenario, the LsaLookupSids function may return the old user name instead of the new user name. This behavior may prevent the application from working correctly.
