You transfer a file between a Windows Vista-based client computer and a file server that is running a previous Windows operating system. Then, the Windows Vista-based client stops responding. This problem occurs if the following conditions are true:

•	Windows Vista and the file server use the Server Message Block (SMB) 1.0 protocol to transfer the file.
•	The network connection between the Windows Vista-based client computer and the file server is lost when you transfer the file. For example, the network cable is unplugged when you transfer the file.

Note When you transfer a file between a Windows Vista-based client computer and a file server that is running a previous Windows operating system, Windows Vista uses the SMB 1.0 protocol to transfer files.
