File corruption occurs under a stress situation when the CopyFileEx function is used to copy a file between two computers that are running Windows Server 2008 or Windows Vista
Consider the following scenario:
- You have two computers that are running Windows Server 2008 or Windows Vista.
- An application or service uses the CopyFileEx function to copy files from one computer to the other computer.
- Server Message Block (SMB) 2.0 compounded requests are used to copy files.
- IP version 6 (IPv6) addresses are used during the file copying process.
In this scenario, under a stress situation, file corruption may occur while copying files.
