SYMPTOMS
The LogonUser function can cache local accounts, which may cause cached domain account information to be deleted. If this occurs, users who log on with cached credential may no longer be able to log on.



CAUSE
This issue can be caused by programs that use the LogonUser function and use a local account. Passing an empty string for lpszDomain to LogonUser may generate invalid cached credentials for the logged-on user.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
