Error message during synchronization of offline files on a Windows XP-based computer: "Unable to Make 'filename.ext' available offline"

Consider the following scenario:

• On a Windows XP-based client computer, you map a network share.
• You create a folder on the network share, and then you make the folder available offline.
• This folder contains many files.

When you try to synchronize the folder in this scenario, you receive an error message that resembles the following:This problem frequently occurs when the offline folder is synchronized for the first time after you click to select the Make available offline check box.

This problem occurs because of a timing issue in the Cscdll.dll file.

A hotfix is available to resolve this problem.

Note You must reinitialize the offline files cache after you apply this hotfix. For information about how to do this, see the "More Information" section.
