Symptoms
Consider the following scenario:
-
You configure a server message block (SMB) server on a Windows Embedded Compact 7-based device.
-
You connect to the device from a desktop computer that uses the SMB version 2 protocol. For example, the desktop computer has Windows Vista or Windows 7 installed.
-
One or more applications or processes copy files into a shared folder on the device.
In this scenario, the copied files may become corrupted. Note This problem occurs only when you copy files from a client that uses SMB version 2. The larger the files are, the more likely the problem is to occur.
Cause
This problem occurs because a critical section is used incorrectly when multiple threads or processes write data to the same file. This causes a thread or process to write data to an incorrect location in the file. Therefore, the file becomes corrupted.
