Consider the following scenario:

• On a Windows Vista-based computer, you copy files to or from another computer on a network.
• This other computer is a Microsoft Windows XP-based computer or a Microsoft Windows Server 2003-based computer.
• These files are each 100 megabytes (MB) or larger.
• You use Windows Explorer to copy the files. For example, you use a drag-and-drop operation in Windows Explorer to copy the files.

In this scenario, the file transfer operation may be slightly slower than expected. This problem occurs only in certain hardware configurations. This problem does not occur when you copy files to or from another Windows Vista-based computer.
