Article: Q236944
Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): kbWinNT4sp6fix

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 4.0, Terminal Server Edition 
- Microsoft Windows NT Server version 4.0 
- Microsoft Windows NT Workstation version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you run a program from a write-protected floppy disk and then quit the
program, you may receive the following error message:

  System - Write Protect Error

  The disk cannot be written to because it is write protected.
  Please remove the write protection from the volume in drive A:.

If the floppy disk is not write-protected, the error message does not occur.

CAUSE
=====

When a program is run from a floppy disk, Windows handles the program file like
a modified page. After the program is quit, the modified page should be removed
without file input/output (I/O). The problem occurs because Windows attempts to
write the page to the floppy disk like a modified data page.
