SYMPTOMS
========

When you open an HTM file using WordPad and make a change, and then open
Internet Explorer and type in the Web site and path to the HTM file, the
following error message occurs when you attempt to save the changes in WordPad:

   The Document your_page.htm is in use by another application and cannot be
   accessed.

CAUSE
=====

Internet Information Server (IIS) opens HTM files to read them and deliver the
content to Web clients. When WordPad opens a document, it blocks both read and
write permissions on the file by setting the Deny write and Deny read flags.
Because IIS has the file open for read, the WordPad request fails. If an
application attempts to open the file with only the Deny write flag, the system
will return the file without an error.

Reviewing network trace information reveals that the IRP making the open call
uses a Deny write Deny read. IIS respects system file locking if you open a file
with Deny read Deny Write attributes. IIS will gracefully respect this and
return an appropriate message.

WORKAROUND
==========

Use another editor to make the necessary changes. Notepad or Visual InterDev are
two of the alternative editors that Microsoft offers.
