SYMPTOMS
You may receive an error message or a blue screen when a program calls the Win32 API GetFileInformationByHandle for a file residing on an offline drive. This generally occurs when you are copying data to or from an offline drive (that is, a drive which is configured for Client-Side Caching or CSC).



CAUSE
The error occurs in adjusting the buffer size after getting file information for files that are in a disconnected state. This causes subsequent code to behave as if there is more memory than actually exists and the program writes beyond the buffer.



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:

STATUS
Microsoft has confirmed that this is a problem in Microsoft Windows 2000. This problem was first corrected in Windows 2000 Service Pack 1.
