Adobe Flash forms do not display when Adobe ColdFusion MX 7 is configured with IIS NTLM authentication, based on the instructions in TechNote tn_18516.
Enabling the Check That File Exists option for the jrun_iis6_wildcard.dll extension will cause Adobe Flash forms to not display. This problem occurs because ColdFusion creates CFSWF files for the Adobe Flash forms in memory. When the Check That File Exists option is enabled, IIS tries to look for CFSWF files and cannot find them, causing the Adobe Flash forms to fail.
This issue is fixed in ColdFusion 7.0.1. Follow the instructions below to get NTLM working with Adobe Flash forms.
Note: The above steps work for IIS and ColdFusion server on the same machine. For a distributed configuration, the IIS webroot needs to be a shared directory for ColdFusion and IIS machines, as ColdFusion needs access to write .cfswf file to the IIS webroot.
For those using ColdFusion MX 7.0, upgrade to ColdFusion 7.0.1/7.0.2 and follow the instructions above.
