SYMPTOMS

The CopyFile function fails and GetLastError returns ERROR_ACCESS_DENIED when you try to copy a read-only file to a core SMB server (such as a LAN Manager for UNIX server) or to a Netware server when the client computer uses real-mode network drivers. The destination file is created as a read-only file and is zero in length.

CAUSE

This error message occurs because there is a mismatch between the way that the Windows 95 or Windows 98 redirector accesses files and the way that these servers expect this access.

RESOLUTION

Remove the read-only attribute before calling the CopyFile function to allow the file to be copied correctly. After the copy is complete, then the read-only attribute can be restored.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
