we have 3 servers (win2003, IIS6, CFMX7) and none of them have had problems
generating/displaying flash forms. But last week forms generated by one of the
servers no longer display in a browser - all you see is a blank space where the
form should be. There are no error messages or anything I can find to indicate
that there is a problem. The same page works fine on the other 2 servers and
the source code delivered to the browser (view source) appears to be indentical.

The w3 logs on the problem server indicate a 404 error (page not found) when
trying to load the generated content: 1024633941.mxml.cfswf

The only thing change made to this server recently was implementing NT
authentication per this technote:

ColdFusion MX (all versions): Implementing NT authentication for ColdFusion
templates with IIS Web Server
http://www.macromedia.com/go/tn_18516

Have used the simple form example in the getting started code snippets:

<cfif not isDefined("form.submit")>
<br><br>
<cfform action="#cgi.script_name#?#cgi.query_string#" method="POST"
format="Flash" timeout="1800" width="400" height="300">
<cfinput name="firstName" size="20" type="text" label="First Name" />
<cfinput name="lastName" size="20" type="text" label="Last Name" />
<cfformgroup type="horizontal">
<cfinput name="submit" value="Submit" type="submit" label="Submit" />
<cfinput name="reset" value="Reset Form" type="reset" label="Reset Form" />
</cfformgroup>
</cfform>

<cfelse>
<br><br>
Information submitted from form:
<br><br>
<cfoutput>
Name: #form.firstName# #form.lastName#
</cfoutput>
<br><br>
<a href="javascript:history.back();">Return</a>
</cfif>


any idea what might be wrong?

I have also foind that Flash Forms within a table will not display (only seems
to be a problem in IE), unless you set the table height to 100%. It may also
require you to set width to 100% as well. Weird.

We had the same problem last week and traced it to a Microsoft patch that had
been installed for the win2003 service pack 1. Check for any patches that were
installed and if you need more information please email me and I will check
with our IT guys to get more specifics.

Bob, I am told that if you are running automatic patch updates on Win2003 after
you have installed Service Pack 1 the updater will apply a security patch
called Data Execution Prevention. Under the Properties/Advanced/Performance
Settings it creates a new tab called the same thing and has two options, one
option applies the security to everything and the other apllies it to core
windows services only. Set this to core windows services.

I am not sure if you are dealing with the same problem or not but this is how
we fixed our problem which sounds very similar to yours.

re"if you need more information please email me and I will check with our IT
guys to get more specifics. "

yes please provide more details.
We have entered a bug report on this but have not heard from Macromedia.

Thanks

Bob

I am a colleague of Bob.
Checking 'Verify that File exists' is exactly what we do. We want this because
we apply NTLM authentication. If this is unchecked, the security control fails.
I sent Macromedia bug reports on this issue twice, and never heard anything
from them.
This is a bug in my view. Flash forms should be able to display on site where
NTLM or negotiate authentication is in place.
