- Microsoft Windows 2000 Professional Edition
- Microsoft Windows 2000 Advanced Server
SYMPTOMS
On your Microsoft Windows 2000 Service Pack 4 (SP4)-based computer, if you use the WriteFile function to write data to a file that is located on a network share, and then you set the attributes of the file by using the SetFileAttributes function, you experience all the following symptoms:
- Not all the data is written to the file. The size of the file that is located on the network share is smaller than expected.
- You do not receive an error message, and no error messages are logged to the event log.
- If you perform a Network Monitor trace of the operation, the size of the file is truncated to the same size that is returned to the CreateAndX request in the Windows 2000 Server Message Block (SMB) packet.
- You may not be able to open, to rotate, or to view the file on the network share by using the Microsoft Office Document Imaging program.
CAUSE
This problem occurs in situations where SMB incorrectly processes multiple open operations of the file.

WORKAROUND
To work around the Microsoft Office Document Imaging issue that is described in the "Symptoms" section, disable opportunistic locking. Microsoft recommends that you disable opportunistic locking on the client computer that is experiencing this issue instead of on the server. By doing so, server performance is not affected. For additional information about how to configure opportunistic locking in Windows, click the following article number to view the article in the Microsoft Knowledge Base:

To work around the file-size-truncation issue that is also described in the "Symptoms" section, use the FlushFileBuffers function before you use the SetFileAttributes function. When you do so, you force data to be written to the file.
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section of this article.
