SYMPTOMS

On a computer that is running Windows 7 or Windows Server 2008 R2, an application calls the GetTempFileName function to create a temporary file. However, the GetTempFileName function fails, and you receive some transient errors that resemble the following:
Access to the path is denied.
You do not have access to <filepath>.

CAUSE

This issue occurs because the GetTempFileName function handles a duplicated file name incorrectly.

When the GetTempFileName function tries to create a temporary file name, it checks whether a duplicate file name already exists. If the GetTempFileName function finds a duplicated file name and the file is pending for deletion, the GetTempFileName function handles the duplicated file name incorrectly and fails altogether with the "ERROR_ACCESS_DENIED" error code.

The expected behavior is that the function retries to create another temporary file name.
