Data is not completely written to files that are located on a network share after you set the attributes of the files in Windows XP Service Pack 1 (SP1)

On your Microsoft Windows XP Service Pack 1 (SP1)-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 notice the following symptoms:

• Not all data is written to the file. The size of the file that is located on the network share is smaller than you 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 XP 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.

This problem occurs in situations where SMB incorrectly processes multiple open operations of the file.
